Rotating electric machine

A rotating electric machine comprising:

• a field element that has a plurality of magnetic poles of which polarities alternate in a circumferential direction;
• and
• an armature that includes
• an armature core that has a circular cylindrical shape, and
• an armature winding of multiple phases that, between an inner circumferential side and an outer circumferential side of the armature core, is assembled on a same side as the field element,
• the field element and the armature being provided so as to oppose each other in a radial direction with an air gap therebetween, and
• either of the field element and the armature serving as a rotor, wherein:
• the armature winding has a coil-side conductor portion that opposes the magnetic pole of the field element in the radial direction, and the coil-side conductor portions are arranged in an array in the circumferential direction;
• and
• the armature winding is provided with a protruding portion that, between an inner side and an outer side in the radial direction, protrudes towards the field element, and is located further towards an outer side in an axial direction than the coil-side conductor portion is.
