To provide an electric tool and a power tool which prevent a rise in the temperature of a motor, reduce production cost, and decrease a size.
An electronic pulse driver 1 includes the motor 3, switching elements Q1 to Q6 for controlling the rotation of the motor 3, a thermistor 33B for detecting the temperature of the electronic pulse driver 1 and a light 2A for illuminating a front part to operate as an illumination.
