6 . The manufacturing method according to claim 1 , wherein the first uplift portion includes a base portion and a protrusion portion.
7 . The manufacturing method according to claim 1 , wherein the first uplift portion is formed by a vacuum shaping method.
8 . The manufacturing method according to claim 1 , wherein the first uplift portion is formed by a press shaping method.
9 . The manufacturing method according to claim 1 , wherein the first uplift portion has a thickness of 5 mm or smaller.
10 . The manufacturing method according to claim 1 , wherein the first uplift portion has a thickness thinner than a thickness of the support portion.
11 . The manufacturing method according to claim 1 , wherein the first uplift portion has a thickness 90% or smaller with respect to a thickness of the support portion.
12 . The manufacturing method according to claim 1 , wherein the processed member includes two or more first uplift portions.
13 . The manufacturing method according to claim 12 , wherein a minimum distance between the two or more first uplift portions is 10 mm or smaller.
14 . The manufacturing method according to claim 1 , wherein the plate member is made of glass.
15 . A plate member comprising: a first uplift portion, a support portion connecting to the first uplift portion, and an alignment mark, wherein
the plate member comprises a first main surface and a second main surface,
the first uplift portion is a projection portion in the first main surface and a portion in the second main surface, corresponding to the projection portion is a recess portion, and
the first uplift portion has a line shape in a top view.
16 . The plate member according to claim 15 , wherein the first uplift portion comprises a base portion and a protrusion portion.
17 . The plate member according to claim 15 , wherein the first uplift portion has a thickness of 5 mm or smaller.
18 . The plate member according to claim 15 , wherein the first uplift portion has a thickness thinner than a thickness of the support portion.
19 . The plate member according to claim 15 , wherein the first uplift portion has a thickness 90% or smaller of a thickness of the support portion.
20 . The plate member according to claim 15 , comprising two or more first uplift portions.
21 . The plate member according to claim 20 , wherein a minimum distance between the two or more first uplift portions is 10 mm or smaller.
22 . The plate member according to claim 15 , wherein the first uplift portion is endless in a top view.
23 . The plate member according to claim 15 , made of glass.
24 . An opening member comprising a plate having a first main surface and a second main surface, wherein
the plate comprises an opening portion and a structural portion forming and supporting the opening portion, and
a top-view projected shape formed by an end surface of the opening portion, on the first main surface side, is different from the top-view projected shape on the second main surface.
25 . The opening member according to claim 24 , wherein a top-view end surface shape formed by an end surface of the opening portion on the first main surface side has a relation of being included in a top-view end surface shape formed by an end surface of the opening portion on the second main surface side.
26 . The opening member according to claim 24 , wherein the plate further comprises a base portion protruding toward the plate on the first main surface side of the plate, and the opening portion is provided on the base portion.
27 . The opening member according to claim 24 , wherein the structural portion has a thickness of 5 mm or smaller.
