Abstract
A power tool includes a small-size lithium ion secondary battery used as its driving source, and at least one lithium ion secondary battery having a diameter of 14 mm is disposed inside a grip portion of a main body of the power tool. The lithium ion secondary battery has a sufficient output characteristic required for driving the power tool. When a switch installed in the main body of the power tool is operated by a user, electric power is supplied to a driving unit including a motor so that the power tool is activated. The lithium ion secondary battery is of a pack type, or is directly housed inside the grip portion, and the grip portion, which houses three of the lithium ion secondary batteries, is designed to have a diameter of 51.8 mm or less.
