Abstract:
This joined body includes: a metal member (12) having a joining surface (15) with depressions (16) formed therein; and a resin member (14) that is joined to the metal member at the joining surface. The joined body comprises an intersecting-direction uneven section (181) and a cover section (24). The intersecting-direction uneven section is included in a depressed surface formation section (20) in which a depressed surface (161) of the metal member that faces the depression is formed. The intersecting-direction uneven section is uneven in a direction intersecting with a depth direction (Ds) of the depression. The cover section forms a surface layer of the depressed surface formation section and covers the intersecting direction uneven section. The cover section forms a layer thinner than an uneven depth (H1) of the intersecting-direction uneven section, and has a porous structure, in which the porous structure of the cover section is filled with the resin member.
