Abstract
A fluid injection valve has: a valve body that is provided with an opening portion at one axial end thereof and is for starting and stopping a supply of a fluid out of the opening portion; and an injection port plate having a plurality of injection ports that penetrate therethrough, the injection port plate being fixed on the one axial end of the valve body to form a fluid chamber between itself and the valve body to accumulate the fluid therein and to which at least a part of the injection ports opens. A circumferential surface of the fluid chamber recedes toward the injection ports so as to decrease a cross-sectional area of the fluid chamber that is taken along a radial direction of the injection port plate and to reserve a predetermined length of distance between itself and the injection ports.
