To provide a solenoid feed water valve suppressing increase of time required until closing the valve due to vibrations of a diaphragm type valve element occurring at the time of closing the valve.

This solenoid feed water valve comprises: a cylindrical valve seat 9 provided on a valve port 8 formed between an inflow chamber 5 and an outflow chamber 7; the diaphragm type valve element 13 opening/closing the valve port 8; a connecting hole 16 communicating the inflow chamber 5 and a pilot chamber 14; a pilot hole 15 communicating the pilot chamber 14 and the outflow chamber 7; and a plunger 18 opening/closing the pilot hole 15. When the pilot hole 15 is closed and the valve port 8 is changed from an opening state to a closing state, the valve element 13 opposes to an outer peripheral surface 31 of the valve seat 9 over a specified distance f by keeping a clearance d in a constant interval before the seating of the valve element 13 to the valve seat 9, and a first guide member 30 restricting a water passing flow rate from the inflow chamber 5 to the outflow chamber 7 to be a constant flow rate smaller than a water passing flow rate restricted by a water amount restricting hole 6, by the clearance d is provided.
