摘要： A rare earth bonded magnet comprises a rare earth-iron-based magnetic powder and a thermosetting resin composition. The thermosetting resin composition is obtained by blending a dicyclopentadiene type epoxy resin as a base resin and dicyandiamide as a curing agent. The dicyclopentadiene type epoxy resin includes a predetermined structure wherein an average value of a repeating unit n is 1 to 3.
