Rotating electrical machine

A rotating electrical machine comprising:

• an annular stator core;
• a coil that is wound around the stator core and includes a first coil end portion that protrudes from one end surface of the stator core and a second coil end portion that protrudes from the other end surface of the stator core;
• a first coolant passage that is a coolant passage formed around the first coil end portion;
• a second coolant passage that is a coolant passage formed around the second coil end portion;
• a cover body that forms a gap that communicates the first coolant passage with the second coolant passage on the inside of the stator core;
• and
• a plurality of connecting wires that are provided in the first coolant passage, each of the connecting wires extending at an angle from the radial outside of the stator core to the radial inside of the stator core, when viewed from the axial direction of the stator core, and connecting a beginning of the coil to an end of the coil,
• wherein the direction in which coolant flows through the first coolant passage is the same as the direction in which the plurality of connecting wires extend at an angle from the radial outside of the stator core toward the radial inside of the stator core, in the circumferential direction of the stator core, and the flowrate of coolant in the first coolant passage is set larger than the flowrate of coolant in the second coolant passage.
