Stator, electric motor, and air conditioner

An electric motor comprising:

• a sensor substrate attached to one end of a stator core in an axial direction of the stator core, the sensor substrate being provided with a bearing through hole for allowing a bearing of a rotor to pass and being provided with a notch on a periphery, the notch being used for leading out a power supply lead and a sensor lead;
• a sensor-lead board-in connector disposed between the bearing through hole and the notch on a surface on an opposite side of a stator core side of the sensor substrate, the sensor lead being connected to the sensor-lead board-in connector;
• and
• a power-supply-lead board-in connector disposed on the surface on an opposite side of the stator core side of the sensor substrate such that the power-supply-lead board-in connector faces the sensor-lead board-in connector with the bearing through hole therebetween, the power supply lead being connected to the power-supply-lead board-in connector.
