Zusammenfassung:	To provide a fuel injection valve including means for uniformizing flow rates of fuel among a plurality of nozzles.SOLUTION: A fuel injection valve 100 includes: a plurality of nozzles 201-206; and a valve element 110 and a seat part 107 cooperating with each other to open and close a fuel passage 108 to the nozzles 201-206. In the fuel injection valve, a communication part 208 is configured so that at least two nozzles 202, 203 of the nozzles 201-206 respectively communicate between inlet surfaces 202e, 203e and outlet surfaces 202o, 203o.SELECTED DRAWING: Figure 2 【課題】本発明の目的は、複数の噴射孔間で燃料の流速を均一化させる手段を備えた燃料噴射弁提供することにある。【解決手段】複数の噴射孔２０１〜２０６と、複数の噴射孔２０１〜２０６への燃料通路１０８を協働して開閉する弁体１１０及びシート部１０７と、を備えた燃料噴射弁１００において、複数の噴射孔２０１〜２０６のうち少なくとも二つの噴射孔２０２，２０３がそれぞれの入口面２０２ｅ，２０３ｅと出口面２０２ｏ，２０３ｏとの間において連通するように、連通部２０８が構成される。【選択図】図２
