PROBLEM TO BE SOLVED : To develop a resin bond type magnet which solves problems such as magnet miniaturization, preciseness, complication of profile and outstanding shock-proof and in which molding shrinkage and moldability are improved and high deformation temperature and high strength are installed, and develop composite for a resin bond type magnet which is used for the above magnet. SOLUTION : The composite for a resin bond type magnet is characterized by carrying out 0.5-5 weight part combination of fiber (C) such as glass fiber, carbon fiber and aramid fiber whose length is 30 μm-10 mm and in which surface treatment may be performed, to composite 100 weight part which composite for a resin bond type magnet contains rare earth magnetic powder (A) of Sm-Fe-N base or Nd-Fe-B base or Sm-Co base in which average particle size is at most 250 μm, and contains resin binder (B) containing thermosetting resin which consists of any one kind out of unsaturated polyester resin, vinyl ester resin, epoxide resin and phenol resin.
