A motor includes: a stator core having a plurality of slots; and a winding inserted into the slot as distributed windings of three phases, wherein an interphase insulation sheet is mounted on a coil end of the winding. The interphase insulation sheet includes: planar insulating portions disposed so as to protrude from each of end surfaces of the stator core; a first leg portion and a second leg portion which integrally connect the planar insulating portions at the end surfaces and which are inserted into the slots; insulating convex portions that protrude toward an inner side in a radial direction of the stator core from the planar insulating portion; and a third leg portion that integrally connects the insulating convex portions at the end surfaces and which are inserted into the slot.
