PROBLEM TO BE SOLVED : To provide a composition for a bond magnet which keeps sufficient flexibility in a low-temperature environment and can increase mechanical strength while maintaining a magnetic property, and the bond magnet produced by molding the composition. SOLUTION : Rare earth transition metal magnet powder (A) is dispersed and mixed with a resin binder (B) to generate a composition for the bond magnet. The resin binder (B) contains at least 50 wt% of a dimerized fatty acid based polyamide block copolymer and/or a dimerized fatty acid based polyether-ester-amide block copolymer.
