PROBLEM TO BE SOLVED: To provide a composition for resin-bonded magnet that has proper magnetic characteristics and degrees of freedom for shape and is superior in rust-preventing characteristic, moldability, mechanical strength, flexibility, heat resistance, etc., and to provide a resin-bonded magnet manufactured by using the composition. SOLUTION: The composition for resin-bonded magnet contains magnetic powder (A) and a resin binder (B), and the powder (A) is coated with an abietic acid-based compound (D1) and a titanate-based coupling agent (D2), after the powder (A) is surface-treated with an inorganic phosphoric acid-based compound (C). |
