1. A stator, comprising:
an iron core formed in an annular shape;
a winding wound around the iron core;
an insulator configured to insulate the iron core from the winding;
a substrate;
a terminal pin configured to connect the winding to the substrate;
an upper connection part configured to electrically connect the winding to the terminal pin; and
a lower connection part configured to electrically connect the terminal pin and the substrate,
wherein the substrate includes
a through hole configured to penetrate the substrate and cause an iron-core facing face of the substrate and a back face of the substrate to communicate, the iron-core facing face facing the iron core, the back face being opposite to the iron-core facing face,
the upper connection part is provided
at a distance from the back face in a direction opposite to the iron core in an outer periphery of the terminal pin, and
the lower connection part is provided in an upper part of the through hole on the back face side in the outer periphery of the terminal pin, arranged independently of the upper connection part.
