To improve connection strength between a sleeve and a magnet composing a rotor in an electrically-driven flow control valve whose valve element is opened and closed while converting rotation of the rotor into linear motion through a screw mechanism.

An electrically-driven flow control valve 10 has a valve body 11 having a valve body 17 inside a valve chamber 15, and an electric motor mounted onto an upper side of the valve body 11. The electric motor has a closed case 31, a stator coil arranged outside the closed case 31, and a rotor 33 arranged in an case inner chamber. The valve body 17 is connected to the rotor 33 by means of a valve shaft 20. Control fluid can be communicated between the valve chamber 15 and an inner chamber of the case 31. A sleeve 34 is arranged inside the rotor 33, while a magnet 39 is arranged outside thereof. The sleeve 34 is adhered to the magnet 39 by adhesive G. They are integrated with each other by a means 135 which escures holding strength.
