A thin plate member 10 has a uniform thickness of not less than 5 µm and not more than 100 µm, includes at least a ceramic sheet, and is formed by sintering. The thin plate member 10 has plural convex portions 11 protruding from one plane P of the thin plate member 10, and plural concave portions 12 caved in from the plane P. Accordingly, the deflection amount obtained when the thin plate member 10 is supported at a predetermined support section of the thin plate member 10 and a load is applied to a load applying section, which is other than the support section, of the thin plate member 10 in a direction orthogonal to the plane P is smaller than the deflection amount of a thin plate member that is flat without having the convex portion 11 and the concave portion 12. That is, the thin plate member 10 which is difficult to be deformed can be provided. |
