<p>Loading a control circuit on a substrate, which is loaded with switching elements, makes interconnection cables and wiring cords unnecessary, improving ease of assembly and reducing housing size. The electric tool uses a housing (1), which has: a body section (2) that houses a brushless motor (10) and an output section (30) to which a tip tool is connected; a handle section (3), one end of which connects to the body section (2); and an accommodating section (4) provided at the other end of the handle section (3). A control circuit (81) is loaded on a FET substrate (80), on which FETs (71) are loaded, and said substrate (80) is disposed inside the body section at the back in the motor shaft direction.</p> |
