Abstract:
An electric power tool, which uses a DC brushless motor as a drive source and controls the DC brushless motor by a switching element, can include a tubular housing main body portion accommodating the DC brushless motor, and a grip portion protruding from a side portion of the housing main body portion. The switching element is arranged inside the grip portion, and is spaced apart from an electronic circuit board for an electronic component for operating the switching element.
