Abstract
Provided are a laminate including a polymer film in which a linear expansion coefficient of at least one surface X is smaller than a linear expansion coefficient of an inside and a metal layer or a metal wire, which is provided on a surface Y side opposite to the surface X of the polymer film; and a polymer film in which a linear expansion coefficient of at least one surface X is smaller than a linear expansion coefficient of an inside.
Claims14
A laminate comprising:
- a polymer film comprising a layer A, and a layer B provided on at least one surface of the layer A,
- wherein the layer B includes an inorganic filler and a surface X opposite to the layer A, and the layer A includes a filler and a surface Y opposite to the layer B, a linear expansion coefficient of the surface X of the layer B is smaller than a linear expansion coefficient of the surface Y of the layer A, and a content of the filler in the layer A is higher than a content of the inorganic filler in the layer B;
- and
- a metal layer or a metal wire is provided on the surface Y of the layer A opposite to the surface X of the layer B of the polymer film.
