The sheet body is orientationally crystallized in a first in-plane axis direction and a second in-plane axis direction orthogonal to each other and having a linear expansion coefficient of 1.0*10E−5/° C. or less in all in-plane directions. A structure surface portion that has a geometric configuration and is formed on at least one of the first surface and the second surface.
