The present invention provides a dynamo-electric machine with which it is possible to strengthen the cooling of a stator coil end part without adversely affecting the cooling of a stator and a rotor. In order to solve this problem, this dynamo-electric machine is characterized in that: a stator coil, which is housed in a plurality of slots formed on the inside diameter side of a stator core, has stator coil end parts formed projecting in the axial direction from end parts of the stator core, and has guide plates installed on the stator coil end parts so as to cover the stator coil end parts; first openings for introducing a cooling medium from a cooler to the stator coil end parts are provided on a stator frame, which is located above the stator coil end parts; and at least one second opening for discharging the cooling medium that has cooled the stator coil end parts is provided to a region of the guide plates located on the axially outer side of axial flow fans.
