PROBLEM TO BE SOLVED: To reduce refrigerant passing noise in dehumidifying operation. SOLUTION: This solenoid valve is formed such that a valve is opened/closed by moving a valve element 4 close to and apart from a valve seat part 6a by an electromagnetic coil 2. A hole 44 and passages 43c and 43b communicating with the hole 44 are formed in the valve element 4 on the refrigerant inflow side. A first porous member 51 breaking air bubbles into ppieces is installed on the inflow side of the hole 44 and a second porous member 52 breaking air bubbles into pieces is installed in the passage 43c. Also, a third porous member 53 breaking air bubbles into pieces is disposed on the downstream side of the refrigerant outflow side, and the first to third porous members 51, 52, and 53 are formed of a tubular or columnar body with uniform diameter. In addition, the density of the porous members is 3.094 g/cm<SP>3</SP>. COPYRIGHT: (C)2005,JPO&NCIPI
