Abstract: <P>PROBLEM TO BE SOLVED: To provide a small-sized solenoid valve in which fluctuations of the internal volume of a valve chamber can be suppressed, and at the same time, the internal volume can be reduced.  <P>SOLUTION: The small-sized solenoid valve 1 is constituted as follows. A valve body 30, in which the valve chamber 8 communicating with first-third ports 5a-5c is internally provided, holds an oscillating member 10 so as to be capable of oscillating. The oscillating member 10 is oscillated by a driving means. Accordingly, a diaphragm 7 fixed to the oscillating member 10 is brought into contact with or separated from valve seats 6b, 6a formed in the valve chamber 8.
