一种粘接结构体,其具备:具有金属部及配置于该金属部的表面的至少一部分的皮膜部的第一构件、第二构件和将上述第一构件与上述第二构件介由上述皮膜部进行接合的粘接剂层,其中,上述皮膜部包含树脂和无机粒子,上述无机粒子由硅铁或含V的非氧化物陶瓷制成,一部分的上述无机粒子朝向上述粘接剂层突出,向上述粘接剂层突出的上述无机粒子中的至少一部分粒径低于上述皮膜部的膜厚。
This bonded structure includes a first member having a metal portion and a film portion disposed on at least a part of a surface of the metal portion; a second member; an adhesive layer for joining the first member and the second member to each other via the film portion. The film portion contains a resin and inorganic particles. The inorganic particles are formed of ferrosilicon or non-oxide ceramics containing V. Some of the inorganic particles protrude toward the adhesive layer. The particle size of at least some of the inorganic particles protruding toward the adhesive layer is less than the film thickness of the film portion.
