Abstract: An electric tool includes: a motor; a control unit configured to control the motor. When the motor is accelerated from a stationary state to a target rotation number, the control unit makes an increase rate of a rotation number of the motor just after energization of the motor starts higher than the increase rate of the rotation number of the motor just before the motor reaches the target rotation number.
