PROBLEM TO BE SOLVED: To provide an ejector device, capable of attaining space saving and simplification in addition to reduction in the component cost and assembling cost of a piping system in a refrigeration cycle using an ejector. SOLUTION: The ejector device includes: an electric valve unit 10 for flow adjustment, which includes a valve element 24, a valve body 20 having a valve seat 22a in which an orifice 23 to be opened and closed by the valve element 24 is opened, and a lifting drive mechanism for adjusting the lift quantity of the valve element 24 to the orifice 23, the mechanism including a rotor 30, a stator 50, etc.; and an ejector unit 60 including a nozzle 71 having a fixed aperture, a mixing section 72 and a diffuser 73. The valve body 20 is extended and enlarged toward the lower side to be used also as an upper fixing section 67 in the ejector unit 60. An upper end inlet of the nozzle 71 is connected and fixed to a portion on the downstream side of the valve seat 22a in the valve body 20, whereby the electric valve unit 10 and the ejector unit 60 are integrated together.
