The plate member is provided with a level difference portion on a first surface of the plate member, and a cut mark portion on a second surface of the plate member. The second surface is on the opposite side of the first surface of the plate member. The plate member is provided with a thick plate portion on a first side of the plate member in a direction in which the plate member extends, and a thin plate portion on a second side of the plate member in the direction in which the plate member extends, with the level difference portion interposed between the first and second sides.
