To effectively reduce refrigerant passing noise, by increasing a capacity of a valve chamber, without increase in size of a valve body or a guide bush.
A straight hole 10 is formed to the valve body 2 of an electric valve A, and the guide bush 4 guiding a valve rod 3 is fixed to the valve body 2 through a tubular spacer 15 press-fitted in an opening part 12 side of the hole 10. A stopper 19 is formed to an inner peripheral flange part 18 disposed on a tip side of the spacer 15, and an end part 24a connected to the valve body 2 of a fluid inlet pipe 24 abuts on the stopper 19 and is restricted. The valve chamber 21 is formed to have a width so that a whole edge of the end part 24a of the fluid inlet pipe 24 enters therein at a position deeper in the hole 10 than the spacer 15. Since a flow of refrigerant from the fluid inlet pipe 24 spreads into the valve chamber 21 with enlarged capacity and stably passes around a valve element 31, the refrigerant passing noise is reduced.
