Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a power tool provided with a brush motor with excellent quality and reliability by preventing breaking of wiring of a stator coil (33a and 33b) due to vibration (exciting force) in the operation.SOLUTION: A thermal shrink tube 46 is used to cover a coil wire at a drawing portion 33b where the coil wire is drawn out to connect a coil portion 33a of a stator core 36 connected to a circuit board 40. The drawing portion 33b covered with the thermal shrink tube 46, is connected to the circuit board 40 with a solder 45, and the thermal shrink tube 46 is thermally shrunk. After being shrunk, an end of the thermal shrink tube 46 is fixed to the circuit board with an adhesive 47, and then the thermal shrink tube 46 is fixed to a drawing portion of the coil 33a with an adhesive 49.
