A rotor of a rotary electric machine includes a rotor core having a magnet insertion hole and a permanent magnet. A magnet insertion hole has an inner diameter side wall surface and an outer diameter side wall surface. A permanent magnet has an inner diameter surface and an outer diameter surface. The rotor further includes a foam adhesive sheet provided at least either between the inner diameter surface and the inner diameter side wall surface or between the outer diameter surface and the outer diameter side wall surface. The foam adhesive sheet includes a foam layer and an adhesive layer stacked in a radial direction. The foam layer is closely fixed to the permanent magnet. The adhesive layer faces the magnet insertion hole. The foam layer is foamed, the adhesive layer closely contacts with the magnet insertion hole, and the permanent magnet is fixed to the magnet insertion hole.
