PROBLEM TO BE SOLVED: To provide a composition of a excellent moldability and mechanical strength by comprising a denatured polyamide, which is a mixture of a terminal group denatured polyamide resin having a specified number average molecular weight, being denatured by a monocarboxyl group hydrocarbon and terminal group denatured polyamide resin having a specified number average molecular weight. SOLUTION: A mixture comprises a denatured polyamide resin of number average molecular weight of at most 10000 and a denatured polyamide resin of number average molecular weight of at least 30000. Mixing ratio thereof is, based on 100 pts.wt. of magnetic powder having an anisotropic magnetic field (HA) of 50kOe, 2-48 pts.wt. as denatured polyamide resin having a number average molecular weight of at most 10000, and 2-48 pts.wt. as denatured polyamide resin having a number average molecular weight of at least 30000. Further, the total mixing amount is 4-50 pts.wt., and an additive of polyolefinic resin and/or polyolefinic copolymer resin is added in the radio of 0.5-50 pts.wt. |
