PROBLEM TO BE SOLVED: To provide a rotary machine wherein heat generated in coils is likely conducted to a stator and radiativity is enhanced. SOLUTION: The rotary machine includes a stator core formed by laminating a plurality of electromagnetic steel plates. Conductors are wound around slots of the stator core to form coils. A thermosetting resin containing inorganic ceramic filler is impregnated and set up between the conductors of the coils, between the conductors and the slots, and at coil ends. A thermosetting resin whose coefficient of thermal conductivity is not less than 0.6 W/m.K is used for the thermosetting resin. Filler powder whose coefficient of thermal conductivity is not less than 5 W/m.K is used for the filler.
