Abstract: The rotary machine includes a rotor rotatably provided and a resin-molded stator. The stator includes a stator core, a coil, and a mold portion. A tooth portion in the stator core includes first and second facing portions. The first facing portion includes a first facing surface where an air gap with the rotor becomes a first distance. The second facing portion is integrated with the first facing portion in the circumferential direction centered at the rotation axis of the rotor, and includes a second facing surface where the air gap becomes a second distance wider than the first distance. The second facing portion includes a groove portion on the second facing surface. The mold portion includes a first mold portion. The first mold portion covers the second facing portion, is provided at the groove portion, and includes a third facing surface where the air gap becomes the first distance.
