Abstract
A laminate produced by laminating a plurality of materials having different linear expansion coefficients via an adhesive agent and is less liable to warp after the adhesive agent is heat-cured. The laminate has a structure including a first material, an adhesive agent layer, and a second material. The first material and the second material have different linear expansion coefficients, and the adhesive agent layer contains an adhesive agent having a warpage reduction index of not less than 30 as calculated from the following expression (1):Warpage reduction index=100−()×100 (1).
