PROBLEM TO BE SOLVED: To provide a polyamide resin-based molding material having low water absorption, excellent dimensional stability and chemical resistance, excellent molding processability, and excellent slidability without blending a sliding imparting agent. SOLUTION: To 100 parts by mass of a copolymerized polyamide resin (A) comprising (a) 50 to 98 mol% of decanterephthalamide units and (b) 50 to 2 mol% of undecanamide units or / and dodecanamide units, It is a resin composition containing 30 to 150 parts by mass of the inorganic filler (B) and not containing a sliding agent. A test piece obtained by injection molding of the resin composition under the conditions (a) below is as follows. A polyamide resin composition for a sliding member, which satisfies (b). (A) Mold temperature 120 ° C, thickness 2mm flat plate, (b) Dynamic friction coefficient 0.40 or less [Selection figure] None |
