PROBLEM TO BE SOLVED: To provide a liquid injection valve capable of securing proper mix ratio of liquid and gas by preventing injected liquid from adhering to a nozzle member and a wall surface of a gas passage. SOLUTION: An angle formed by of a tangential line, in the vicinity of an outlet edge 34 of a nozzle space 22, to a partition wall 28 and a center line A-A of a valve element 12 is set smaller than an angle formed by a tangential line 5, at the position where the valve element 12 is in contact with a valve seat 18, to an outer wall and the center line A-A of the valve element 12. Consequently, since liquid injected outward from the outlet edge 34 of the nozzle space 22 is injected more inward than the direction of the tangential line 5 to the outer wall of the valve element 12, spread of the liquid is prevented, adhesion of the liquid to the wall surface of the gas passage is eliminated and a trouble of variation of mix ratio liquid and gas can be prevented.
