PROBLEM TO BE SOLVED: To provide an electromagnetic valve which shortens length of atomization while minimizing flow rate and can secure strength of a tip of a nozzle.SOLUTION: An electromagnetic valve includes a valve body 114, a seat part 4 on which the valve body 114 is seated and a fastening valve 116 which is provided on the downstream side of the valve body 114 and is formed of a plurality of ejection holes 117. A downstream side tip part 116a of the fastening valve 116 is formed such that a thickness increases toward the inner circumferential side from the outer circumferential side on an axial direction cross-section which passes through a center axis C of the valve body 114. An axial direction length L of the plurality of ejection holes 117 are formed so as to be longer than a thickness dmax of a portion of which the thickness gets to largest on a downstream side tip part 116a.SELECTED DRAWING: Figure 1 【課題】小流量化しながら噴霧の長さを短くするとともにノズルの先端の強度を確保することができる電磁式弁を提供する。【解決手段】電磁弁は、弁体１１４と、弁体１１４が着座するシート部４と、弁体１１４の下流側に設けられ、複数の噴射孔１１７が形成される固定弁１１６を備える。固定弁１１６の下流側先端部１１６ａは、弁体１１４の中心軸Ｃを通る軸方向断面において外周側から内周側に向かって厚みが増加するように形成される。複数の噴射孔１１７の軸方向長さＬは、下流側先端部１１６ａにおいて最も厚みが大きくなる部位の厚みｄｍａｘよりも長くなるように形成される。【選択図】図１
