INSULATION SHEET, STATOR COIL AND ROTARY ELECTRICAL MACHINE

摘要

PROBLEM TO BE SOLVED: To provide: an insulation sheet which can improve heat conductivity while maintaining excellent electrical insulation property; a stator coil provided with the insulation sheet; and a rotary electric machine provided with the stator coil. SOLUTION: The insulation sheet 10 includes: a clay mineral layer 20 comprised of resin 22 containing clay mineral 21; a base layer 30 laminated on one surface of the clay mineral layer 20 and comprised of reinforcing base material 33 to which resin 32 containing filler material 31 with a heat conductivity of≥1 W/(m K) is impregnated; and a heat conductive layer 40 formed on the other surface of the clay mineral layer 20 and comprised of resin 42 containing filler material 41 with a heat conductivity of≥1 W/(m K).
