An ON/OFF magnet attachment vice jaw is provided to prevent separation of a support block, and increase machining stability and precision of a workpiece. An ON/OFF magnet attachment vice jaw includes a movable jaw(1), a stationary jaw(1'), a switch rod(2), and a magnetic body. The movable jaw and the stationary jaw are rotated by magnets(22) having a wrench groove(21). The magnets having different polarities are installed at the switch rod. The magnetic body is exposed from side surfaces of the movable jaw and the stationary jaw. A magnetic body case is installed at an outer periphery of the magnetic body to prevent malfunction of the magnetic body. The switch rod is rotated to transmit the magnetic force to the magnetic body.
