A power tool includes a motor housing, a motor, a motor-side terminal, a switch block, and a switch-side terminal provided on the switch block to be connected to the motor-side terminal. A hollow tubular member is provided on one of the motor housing and the switch block and extends in a longitudinal direction of the motor housing, and a fitting member is provided on the other of the motor housing and the switch block and fitted in the tubular member. The motor-side terminal and the switch-side terminal are connected to each other within a hollow of the tubular member. As long as the motor-side terminal and the switch-side terminal are at least connected to each other, the tubular member and the fitting member are held in the fitted state so that a connection between the terminals is isolated from the outside of the tubular member.
