A power tool includes a motor including a rotor and a stator disposed around the rotor; an output shaft to which a tip tool is attached and that is rotated by power generated by the motor; a torque sensor unit that is disposed between the stator and the output shaft in a front-rear direction parallel to a rotation axis of the motor and that is coupled to the output shaft; an amplifier circuit that amplifies a detection signal of the torque sensor unit; and a housing including a motor housing part for housing the motor and a grip part. The torque sensor unit is disposed forward of the stator. The grip part is disposed downward of the motor housing part. The amplifier circuit is disposed upward of the grip part.
