PROBLEM TO BE SOLVED: To provide a brushless vibration motor unit for a portable information electronic apparatus such as a portable telephone. SOLUTION: The brushless vibration motor unit is constituted of a rotor formed from a bipolar permanent magnet having a rotor axis, a stator having a rotor hole into which the rotor is inserted, a coil magnetically connected to the stator and obtained by winding a wire, and a brushless vibration motor being fixed to the rotor axis and having a weight for eccentricity. Further, the bruhless vibration motor unit has, as a constituent element, a driver circuit IC substrate mounted with a driver circuit IC so as to drive the brushless vibration motor.
