1. A dynamoelectric machine comprising:
a winding;
a stator core including a slot in which the winding is installed;
a cover part that covers the stator core; and
a crossing part that is a space formed between the cover part and the stator core,
wherein, in the crossing part, an end portion of the winding in an axial direction is exposed, and a filling member is disposed between a side surface of the winding in a radial direction and an inner side surface of the cover part in the radial direction,
the dynamoelectric machine comprises: a shielding member between the winding and the filling member, and
the filling member is a semi-solid resin containing a foaming agent.
