Stator, motor, and air conditioner

A stator to which a power supply lead wire for supplying electric power is connected, the stator comprising:

• a stator core;
• an insulation part covering the stator core;
• a winding wound around the stator core via the insulation part;
• a winding terminal fixed on an outer wall of the insulation part and connected to the winding;
• a circuit board having a first surface facing the stator core, a second surface provided on a side opposite to the first surface, a power-supply-terminal insertion hole communicating between the first surface and the second surface at a position facing the winding, and a winding-terminal insertion hole communicating between the first surface and the second surface and being arranged on a radially outward position relative to the power-supply-terminal insertion hole in a radial direction of the stator core;
• a power supply terminal exposed on the first surface via the power-supply-terminal insertion hole to connect to the power supply lead wire arranged on the side of the second surface;
• and
• a wiring pattern provided on the first surface and connecting the winding terminal and the power supply terminal to each other, wherein
• the winding terminal is electrically connected to the wiring pattern by soldering the winding terminal in a state of being inserted into the winding-terminal insertion hole from the first surface of the circuit board.
