Abstract
A power tool including a brushless motor having a sensor circuit board has higher durability. The power tool includes a housing, a brushless motor including a rotor having a rotational shaft, a stator, and a sensor circuit board fixed to the stator and having a rotation detecting element that detects rotation of the rotor, and receiving the rotational shaft through the sensor circuit board, and a bearing held in the housing and supporting the rotational shaft. The bearing is located to overlap the rotation detecting element in an axial direction of the rotational shaft.
