In a fluid injection valve, a fuel filter is installed in an upstream portion of the housing. A valve element is slidably installed in the housing to lift off and seat on a valve seat provided at a downstream portion of the housing. A passage portion is provided in the housing between the fuel filter and the valve element to face the fuel filter and has an opening portion at an upstream end thereof. An inner width of the opening portion is narrower than a bore of the upstream portion of the housing. A distance between the opening portion and the fuel filter is 4.5 mm or greater.
