A solid fixing resin composition, which has excellent filling properties, and a rotor using the same are provided. The fixing resin composition is used to form a fixing member constituting a rotor which includes a rotor core ( 110 ) which has a laminate formed by lamination of a plurality of plate members, is fixed and installed on a rotating shaft, and has a plurality of hole portions ( 150 ) arranged along the peripheral portion of the rotating shaft, provided in the laminate; a magnet ( 120 ) inserted in the hole portion ( 150 ); and a fixing member ( 130 ) formed by curing a fixing resin composition, filled in the separation portion between the hole portion ( 150 ) and the magnet ( 120 ), the resin composition including a thermosetting resin (A) containing an epoxy resin; a curing agent (B); and an inorganic filler (C), in which the ICI viscosity at 150° C. of the epoxy resin is equal to or less than 3 poises. |
