Abstract
An electric power tool includes a motor, an output unit driven by the motor, a metallic housing, a cover, an electrical part, and a battery mounting portion. The metallic housing houses the output unit and extends forward. The cover is made of resin that covers at least a part of the housing. The electrical part is disposed on a front portion side of the housing. The battery mounting portion has positive and negative terminals to which a mounted battery is electrically connected. On an outer surface between front and rear faces of the housing, a connecting portion of a ground wire connected to the negative terminal of the battery mounting portion is disposed in a conductive state with the outer surface. A partitioning portion is formed in the cover and partitions between a lead wire for electrical component connected to the electrical part and the connecting portion.
