Zusammenfassung:A motor operated valve (1) includes a body, a valve element, a rotor (320), a can (302), and a stator unit (360). The stator unit (360) includes a case (400) having a cylindrical shape and made of resin, a stator (340) mounted in the case (400) and coaxially around the can (302), a circuit board (420) mounted in the case (400), a power supply terminal (422) connected with the circuit board (420), a connector part (402) made of resin and integrally including the power supply terminal (422) therein, and a cap member (440), the cap member (440) and the case (400) forming a space (S) containing the circuit board (420). The connector part (402) is formed integrally with the case (400). A first seal portion is provided between a first open end portion (403) of the case (400) and the cap member (440), and a second seal portion is provided between a second open end portion (410) of the case (400) and the body.
