Metal/resin composite structure and method for manufacturing same

A method for producing a metal-resin composite structure comprising a surface-roughened metal member and a resin member bonded to the metal member and composed of a polyarylene sulfide resin composition, in which the metal member is made of aluminum, copper, magnesium, iron, titanium or an alloy containing at least one of them,

• the method comprising melt-molding the polyarylene sulfide resin composition including a polyarylene sulfide resin (A) and a phenol resin (B) to the metal member at a temperature equal to or higher than the melting point of the polyarylene sulfide resin (A), wherein
• the polyarylene sulfide resin composition is a molded product of a resin composition including a polyarylene sulfide resin (A) and a phenol resin (B) in an amount of 0.05 to 20 parts by mass with respect to 100 parts by mass of the polyarylene sulfide resin (A),
• wherein the phenol resin (B) is a novolac phenol resin which is a thermoplastic polymer having a phenol skeleton,
• wherein the phenol resin (B) has a hydroxyl group equivalent in a range of 80 to 200 g/equivalent, and
• wherein the phenol resin (B) has a softening point in a range of 98 to 180° C.
