Abstract
A power tool includes a stator having a coil, a sensor circuit board attached to the stator and on which a magnetic sensor is provided, the sensor circuit board having a first side facing the stator and a second side opposite the first side, a rotor configured to rotate with respect to the stator, a tool-accessory retaining part configured to be driven by the rotor and a power-supply line configured to supply electrical power to the coil. The power-supply line is connected to the coil without traversing the second side of the sensor circuit board.
