| description | PROBLEM TO BE SOLVED: To provide a resin composition for a bonded magnet excellent in moldability, and a bonded magnet excellent in mechanical strength and heat resistance. SOLUTION: This resin composition comprises a magnetic powder and an aromatic polyamide resin. The polyamide resin has such characteristics that the molar ratio of the amount of remaining terminal carboxyl groups to that of remaining terminal amino groups is 1.0 or lower or that an aliphatic diamine component for producing the polyamide resin comprises a linear diamine and a branched diamine, the molar ratio of the content of the linear diamine to that of the branched diamine being less than 4.0.
