An insulator includes a main body, a latching portion, and a slot. The main body covers a portion of a stator core around which a coil is wound to insulate the stator core from the coil. The latching portion is disposed at an end of a portion of the main body around which the coil is wound to latch the coil onto the main body. The slot is formed so as to expose the coil at a portion of the latching portion on a side where cooling oil for cooling the coil is supplied to the coil.
