Abstract
A rotary electric machine includes: a rotor rotating about an axis; a stator formed by annularly combining cores having electric wires wound therearound and placed on the outer side of the rotor in a direction orthogonal to the axis; and an insulator including an outer portion placed on the radially outer side of the stator; an inner portion placed on the radially inner side of the stator; a trunk portion coupling the outer portion and the inner portion and having the electric wire wound therearound; a recess portion formed in a portion of the outer portion facing the inner portion to accommodate the electric wire; and a wall placed at the recess portion on the side of the inner portion to partially cover the recess portion. The insulator is attached to one end portion of the cores in a direction parallel with the axis.
