Abstract
A battery pack for a power tool includes a housing, at least one battery, a connector, a first antenna, and a first communication circuit. The housing is detachably attachable to a power tool body. The housing includes a first wall, a second wall opposite to the first wall, and a third wall connecting a periphery of the first wall to a periphery of the second wall. The battery is in an internal space of the housing defined by the first wall, the second wall, and the third wall. The connector is nearer the first wall than the battery to feed power from the battery to the power tool body. The first communication circuit performs communication with the first antenna. The first antenna is at the first wall, at the third wall, or in an area in the internal space other than an area between the battery and the second wall.
