Abstract: A rotary electric machine includes a stator core, a coil, and a molded portion. The stator core includes an annular yoke and a plurality of teeth. The teeth protrude radially inward from the annular yoke. The coils are wound around the teeth respectively. The coil includes a coil end that protrudes toward an axially outer side from an axially end surface of the stator core. The molded portion is a resin member that covers the coil end. The molded portion includes a first member. The first member includes a communication portion that communicates inside of the molded portion with outside of the molded portion.

Abstract: A stator includes a stator core, an insulating body, a coil, and a resin-molded product. The stator core includes a circumferentially side surface and an axially upper surface. The insulating body includes a side wall and an upper wall. The side wall covers the circumferentially side surface of the stator core. The upper wall covers the axially upper surface of the stator core. A radially inner side end surface of the upper wall is positioned farther toward a radially outer side than a radially inner side end surface of the side wall. The resin-molded product covers the coil.

Abstract: Communication grooves for communicating an outer circumferential side with an inner circumferential side of a stator core are formed at a contact face, that contacts the stator core, of a three-phase terminal fixing member. Furthermore, a retention part deeper than the communication grooves is formed. When resin is injected, air between the stator core and a stationary mold and between the stator core and a movable mold is discharged to the outside through the communication grooves, and thus it is possible to suppress formation of voids between the stator core and the stationary mold and between the stator core and the movable mold. In addition, the resin expands by releasing its pressure at the retention part, and thus it is possible to suppress the resin from flowing to the outside through the communication grooves.
