Rotating electric machine

A rotating electric machine comprising:

• a stator which has an annular shape centered on a center axis;
• and
• a rotor which is located on one radial side of the stator, the rotor being supported to be rotatable around the center axis,
• wherein the stator comprises:
• a stator core which includes a core back portion having an annular shape centered on the center axis;
• a coil comprising a bundle of coil wires, the coil being disposed on one radial side of the core back portion;
• and
• a resin portion which fixes the coil to the stator core,
• wherein the resin portion comprises:
• a first region which extends in the radial direction along a coil side surface facing the circumferential direction of the coil;
• and
• a second region which extends in the circumferential direction along a support surface facing the one radial side of the core back portion,
• wherein the resin portion includes fillers, each filler has a respective longitudinal direction having a first orientation angle which is defined to be a first inclination angle inclined with respect to the coil side surface in view of an axial direction of the center axis,
• wherein the fillers in the first region comprises a first group of fillers which are smaller in the first orientation angles than 45°, and a second group of fillers which are equal or greater in the first orientation angles than 45°, and the number of the first group of fillers is greater than the number of the second group of fillers.
