Abstract
A metal/resin composite structure includes: a metal member (M) having a fine uneven surface; and a polyamide-based resin member (A) bonded to the metal member (M), and the polyamide-based resin member (A) satisfies the following condition [A1] and condition [A2]: [A1] a glass transition temperature (Tg) observed by a differential scanning calorimeter (DSC) is equal to or higher than 85° C. and equal to or lower than 140° C.; and [A2] a crystallization temperature (Tc) observed by a differential scanning calorimeter (DSC) is equal to or higher than 250° C. and equal to or lower than 292° C.
