Summary:PROBLEM TO BE SOLVED: To provide a synthetic resin magnet composition which is superior in fluidity, in strand strength in a kneading/extruding process, and in molding strength. SOLUTION: The resin magnet composition is composed of surface-treated magnetic material powder and polyamide resin. The synthetic resin magnet composition is composed of 3 to 40 wt.% polyamide-6 resin whose number- average molecular weight is 8.000 to 10,500 and 97 to 60 wt.% magnetic powder.
