In an angle electric power tool 1 in which an output axis P intersects and is orthogonal to a motor axis J, a battery attachment portion 40 is provided to the rear of a grip 30 so as to extend in the rearward direction and a battery pack 50 is configured to be attached to an upper surface of said battery attachment portion 40. Because of this configuration, the battery pack 50 does not directly come into contact with a working surface W, thereby preventing flaws and scratches on the working surface W.
