An electric power tool has a device housing with a rear grip extending in the longitudinal direction of the device housing. The device housing has first opposed housing sides and second opposed housing sides. An electric drive motor and its electronic control are arranged in the device housing. A battery pack compartment arranged in the device housing receives a battery pack that has a parallelepipedal shape and extends in a direction of a height axis, width axis and depth axis. The battery pack is arranged such that the width axis and the height axis extend transversely to the longitudinal axis of the device housing. The battery pack has narrow sides extending approximately parallel and at a minimal spacing relative to the first opposed housing sides, respectively. The battery pack has opposed end faces neighboring the second housing sides, respectively.
