An electric power tool includes a housing, a fan, a tubular portion, and a rectifier. The housing houses a motor. The fan rotates in association with driving of the motor to generate a cooling air for the motor within the housing. The tubular portion is formed in the housing to house the fan. The rectifier is disposed to be opposed to the fan in an upstream side of the cooling air. The rectifier is divided into an inside and an outside in a radial direction of the tubular portion, the outside in the radial direction is formed of the tubular portion, and the inside in the radial direction is formed of a baffle plate assembled to the housing.
