PROBLEM TO BE SOLVED: To provide a high-reliability electric tool that modifies the balancing amount of a rotor for a brushless motor without generating any splash of an adhesive material and without producing defective pieces caused due to the balancing amount of the rotor. SOLUTION: The electric tool includes a motor housing part that includes a tubular housing part, accommodates a brushless motor and includes an inner circumferential part extending to the axial direction of a rotation axis for the brushless motor, and a drive transmission housing part for accommodating a drive transmission mechanism part formed continually at one end of the motor housing part. The brushless motor incorporates a tubular stator having an outer circumferential part and an inner circumferential part that extend to the direction of a rotation axis, and a rotor arranged concentrically within the tubular stator, an adhesive material for the balancing modification being embedded into the rotor.
