| description | [Object] To provide an electric valve capable of restricting a phenomenon in which a melted brazing material rises along an outer periphery of a valve seat and an assembly method thereof. [Solving Means] An electric valve includes: a valve shaft provided with a valve body; a valve seat provided with a valve seat portion with which the valve body comes into contact and from which the valve body separates; a valve main body having the valve seat fixed thereto by soldering; and a stepping motor with a rotor and a stator for elevating the valve shaft, in which a constricted portion is provided at an outer peripheral surface of a side surface of the valve seat. |
