Document Type and Number:

WIPO Patent Application WO/2019/243855

Kind Code:

A1

Abstract:

The problem addressed by the present invention is to increase the adhesive strength in a joined structure in which members comprising different materials are joined by means of an adhesive layer, while minimizing the incidence of cracks in the adhesive layer. This joined structure is provided with two members (1, 2) comprising materials having different coefficients of linear expansion, and an adhesive layer (3) that is interposed between the two members and bonds the two layers. The adhesive layer (3) is provided with at least end sections (3a) in the direction parallel to the surface of the adhesive layer and a center section (3b) in said direction, and the thickness at the end sections (3a) is greater than the thickness at the center section (3b).
