1. A rotary electrical machine, comprising:
a stator core having a plurality of teeth;
a plurality of windings having coils wound around the teeth;
a plurality of coil terminals connected to the winding;
a plurality of external connection terminals connected to the coil terminal and connectable to an external power supply terminal; and
a plurality of terminal holding portions attached to the stator core and configured to hold the coil terminals;
wherein
when a direction parallel to a rotation axis of the rotary electrical machine is defined as an axial direction,
the external connection terminal has a contacted portion that extends in a direction perpendicular to the axial direction and abuts against a contact portion of the coil terminal in the axial direction, and
the terminal holding portion holds the coil terminal so as to be relatively movable in a direction of approaching and separating from the contacted portion.
