Summary:An insulator attached to a core body in an annular shape and multiple teeth protruding from the core body along a radial direction for insulating the teeth and a coil wound around the teeth includes: a tooth end surface covering part covering an axial end surface of the tooth. The tooth end surface covering part includes: an inclined part provided on a front surface of the tooth end surface covering part on a side opposite to the tooth and inclined such that its height from the axial end surface of the tooth gradually changes along the radial direction; and an inclined part parallel part and a tooth parallel part provided on a back surface of the tooth end surface covering part on the tooth side and concave in a direction away from the axial end surface of the tooth.
