PROBLEM TO BE SOLVED: To provide a welding member which is excellent in original properties of a polyamide, such as moldability, heat resistance, toughness, oil and gasoline resistance, abrasion resistance and the like in good balance and is especially excellent in welding strength and to provide a molded item. SOLUTION: The welding member comprises a copolymer of a polyamide resin (A), which consists of (A1) 65-95 wt.% of hexamethyleneadipamide units and (A2) 35-5 wt.% of hexamethyleneisophthalamide units and/or caproamide units and satisfies formula (1): 0<=(weight ratio of caproamide units (wt.%))/(weight ratio of hexamethyleneisophthalamide units (wt.%))<=10 (1). |
