PROBLEM TO BE SOLVED: To provide a multi-nozzle fluid injection valve capable exactly controlling an entrained flow and flow in spraying and forming a stable air-fuel mixture by specifying the injection direction of each nozzle. SOLUTION: An opening 7a at an end in linearly continuous direction is arranged in closer proximity to the axis L of a nozzle main body than the opening position of an adjoining opening 7d. The opening 7d at the other end in linearly continuous direction is arranged further with respect to the axis L of the nozzle main body than the opening position of the adjoining opening 7a. A length L in linearly continuous direction of a spraying group is made greater than an interval B opposing to an adjoining spraying group respectively to assure an air passage B at each spraying group so that the ambient air can exactly flow into the spraying, a stable swirl flow S can be formed and a spray outer shape can be prevented from reducing by eliminating a differential pressure between the inside and outside of spraying.
