Solid-state imaging device and method for manufacturing the same

1. A solid-state imaging device comprising:

a housing in which a base and ribs farming a rectangular frame are formed in one piece by a resin;

a plurality of metal lead pieces embedded in the housing, each of which has an internal terminal portion facing an internal space of the housing, and an external terminal portion exposed at an outer portion of the housing;

an imaging element arranged on the base in the internal space of the housing;

connecting members connecting electrodes of the imaging element to the internal terminal portions of the metal lead pieces; and

a transparent plate fastened to an upper face of the ribs,

wherein the upper face of the ribs is provided with a lower step portion that is lowered along an external periphery; and

the transparent plate is fastened to the upper face of the ribs by an adhesive filled at least into the lower step portion.

2. The solid-state imaging device according to claim 1 ,

wherein a thickness of the metal lead pieces at the position of the internal terminal portion is substantially the same as a thickness of the base, and the external terminal portions are formed on a rear face corresponding to the position of the internal terminal portions.

3. The solid-state imaging device according to claim 1 ,

wherein an outer lateral face of the ribs forms a plane that is substantially perpendicular to a surface of the base, and an end face of the transparent plate is formed substantially flush with the outer lateral face of the ribs.

4. The solid-state imaging device according to claim 2 ,

wherein a thickness of the metal lead pieces that is located below the ribs is thinner than the thickness of the base.

5. The solid-state imaging device according to claim 4 ,

wherein each of the metal lead pieces has a lateral electrode portion exposed at the outer lateral surface of the base and,

the portion under the lateral electrode portion is covered with a resin.
