Rotating electric machine and vehicle wheel using rotating electric machine

A rotating electric machine comprising:

• a field element that includes a magnet portion that includes a plurality of magnetic poles of which polarities alternate in a circumferential direction;
• an armature that includes an armature winding of multiple phases, either of the field element and the armature rotating together with a rotation shaft;
• a power converter that is electrically connected to the armature winding;
• a plurality of electrical components that configure the power converter;
• and
• a housing member that includes a cylindrical portion that is provided on a radially inner side of a magnetic circuit portion that includes the magnet portion and the armature winding, and to which the plurality of electrical components are disposed, wherein
• the cylindrical portion is provided with a coolant passage through which a coolant flows, and
• the plurality of electrical components are arranged in the housing member on a radially inner side of the cylindrical portion, in a circumferential direction along the cylindrical portion.
