PROBLEM TO BE SOLVED: To enhance operability by making a DC brushless motor compact in size in the machine length direction, thereby making an electric tool compact in machine length in the electric tool such as an impact driver employing the DC brushless motor as a drive source. SOLUTION: The machine length of a DC brushless motor M is shortened by locating a bearing 57 for supporting a rotating shaft 53 of a rotor 50 on the inner circumferential side of the electric insulating member 62 of a stator 60.
