An electric tool includes a functional piece, a motor, a case and a fan. The case includes a motor case portion. An airflow inlet and an airflow outlet are formed in the case. When the fan operates, an airflow at the airflow inlet is taken out and is directed to the airflow outlet after the airflow flows through the motor. The motor case portion includes an encircling portion which encircles the motor and an end portion arranged on one end of the encircling portion. A stopping piece stops the airflow from flowing back from one side of the motor to the other side.

The motor case portion includes an encircling portion which encircles the motor and an end portion arranged on one end of the encircling portion. The motor includes a stator, a motor shaft and a rotor. The stator is fixed relative to the case. The motor shaft is rotatably arranged in the case. The rotor surrounds the stator and rotates synchronously with the motor shaft. A stopping piece having a stopping portion is arranged at a first clearance between the rotor and the encircling portion. A projection of the stopping piece in a plane perpendicular to a rotating axis of the rotor is at least partially located outside a projection of the rotor in the plane. The stopping piece stops the airflow from flowing back from one side of the motor to the other side.
