A work machine includes a motor and a sensor disposed in a front unit, a motor controller disposed in a rear unit, a motor power line and a sensor signal line disposed along an operation rod, and a pair of electric connectors. The motor power line includes first and second partial motor power lines disposed along the first and second partial rods respectively. The sensor signal line includes first and second partial sensor signal lines disposed along the first and second partial rods respectively. A first electric connector includes first electric terminals, each of which is coupled with corresponding one of the first partial motor power line or the first partial sensor signal line, and a second electric connector includes second electric terminals, each of which is coupled with corresponding one of the second partial motor power line or the second partial sensor signal line.
