Claim 3:
4. The rotating electric machine according to claim 2, wherein:
the coolant flows into the coolant passage from a coolant recirculation system that includes a coolant recirculation path that recirculates the coolant and a heat releasing apparatus that is provided on the coolant recirculation path;
the coolant passage has an inlet portion into which the coolant flows from the coolant recirculation path and an outlet portion from which the coolant flows into the coolant recirculation path, and is provided in an annular shape along the cylindrical portion so as to connect the inlet portion and the outlet portion in the circumferential direction;
the cylindrical portion is provided with a protruding portion that protrudes on a radially inner side, and the inlet portion and the outlet portion are provided in the protruding portion;
the switch module and the capacitor module are a plurality of electrical modules;
as intervals between the electrical modules that are adjacent to each other in the circumferential direction, a first interval and a second interval that is wider than the first interval are provided; and
the protruding portion is provided in a portion in which the interval between the electrical modules that are adjacent to each other in the circumferential direction is the second interval.
