wherein the first body includes a first protruding part, the second body includes a second groove facing the first protruding part, and the second groove has an inclined surface that is disposed on a bottom surface thereof and of which a distance to the first protruding part in a direction of an optical axis gradually increases toward an outer side thereof, and
wherein the first protruding part decreases in thickness downwardly.
2 . The camera module of claim 1 , wherein a first coupling hole is disposed on a lower surface of the first body, and the substrate includes a second coupling hole facing the first coupling hole and a screw passing through the second coupling hole and coupling the first coupling hole.
3 . The camera module of claim 1 , wherein the first body includes a first ground portion contacting an upper surface of the substrate, and the second body includes a third ground portion contacting a lower surface of the substrate.
4 . The camera module of claim 3 , wherein the first body includes a second ground portion in contact with an upper surface of the substrate.
5 . The camera module of claim 3 , wherein an area of the substrate in contact with the first ground portion and the third ground portion is a ground area.
6 . The camera module of claim 1 , wherein the first body includes a first guide, and the substrate includes a second hole through which the first guide passes.
7 . The camera module of claim 6 , wherein the second body includes a guide hole through which the first guide is coupled.
8 . The camera module of claim 1 , wherein the second body includes a second guide, and the substrate includes a third hole through which the second guide passes.
9 . The camera module of claim 1 , wherein an outer surface of the first body is disposed outwardly from an outer surface of the second body.
10 . The camera module of claim 1 , wherein an outer surface of the first body is disposed outside an outer surface of the second body.
11 . The camera module of claim 1 , wherein the first body includes a first groove disposed inside the first protruding part,
wherein the second body includes a second protruding part facing the first groove, and
wherein the adhesive is disposed between the first groove and the second protruding part.
12 . The camera module of claim 11 , wherein the second protruding part has an inclined surface formed on its outer surface whose thickness becomes thinner as it goes upward.
13 . The camera module of claim 11 , wherein the adhesive is disposed between a side of the substrate and an inner surface of the first body, and between the side of the substrate and an inner surface of the second body.
14 . A camera module comprising:
a lens holder;
a first body in which the lens holder is disposed;
a second body coupled to the first body;
a substrate disposed between the first body and the second body; and
an adhesive coupling the first body to the second body,
wherein the first body includes a first protruding part, the second body includes a second groove facing the first protruding part, and the second groove has an inclined surface that is disposed on a bottom surface thereof and of which a distance to the first protruding part in a direction of an optical axis gradually increases toward an outer side thereof, and
wherein a pattern exposing a metal layer of the first body or the second body is formed on a surface of at least one of the first protruding part or the second groove.
15 . The camera module of claim 14 , wherein the pattern has a structure in which a plurality of metal lines are spaced apart from or connected to each other.
16 . The camera module of claim 14 , wherein the metal layer has a recessed groove shape compared to a surface-treated region.
17 . The camera module of claim 14 , wherein the metal layer forms a grounding region.
18 . A camera module comprising:
a lens holder;
a first body in which the lens holder is disposed;
a second body coupled to the first body;
a substrate disposed between the first body and the second body; and
an adhesive coupling the first body and the second body, the first body comprising a first protruding part, a first groove disposed on an inner side of the first protruding part, and the second body comprising a second groove facing the first protruding part, a second protruding part facing the first groove, wherein the adhesive is disposed between the first protruding part and the second groove and between the second protruding part and the first groove, and wherein a surface of at least one of the first protruding part, the first groove, the second protruding part, and the second groove is formed in a pattern with an exposed metal layer of the first body or the second body.
