摘要：
A fuel injection valve comprises a valve seat, a movable valve element which is seated on or separated from the valve seat, and a nozzle member having a plurality of nozzle holes. At least one of the valve element and valve seat has a curved surface at a contact position where they contact with each other when the valve element is seated on the valve seat. Two or more of the nozzle holes are provided outside an intersection line of a virtual extension surface along a tangential line to the curved surface at the contact position and a surface of the nozzle member.
