Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an electric power tool in which the dustproof performance of a circuit board or a stator coil is improved and the cooling capacity of the circuit board is secured, and to provide a method for manufacturing the electric power tool.SOLUTION: The electric power tool includes a brushless motor for driving a tip tool. The brushless motor has a cylindrically-formed stator 31, a rotor arranged in the stator 31 and a motor drive circuit device 33 connected to the stator 31. The stator 31 has a coil 31B to be connected electrically to the motor drive circuit device 33. The coil 31B is covered with a coating material 31D and the motor drive circuit device 33 is covered with an insulation cover member 33D. The method for manufacturing the electric power tool is also provided.
