Abstract
Provided is a fuel injector that is capable of reducing penetration. The fuel injector of the present invention includes a valve body having a valve body side seat surface, a valve seat side seat surface that abuts on the valve body side seat surface, and an injection hole that is provided downstream of a position at which the valve body side seat surface abuts on the valve seat side seat surface. The valve body has a projection that is formed from the valve body side seat surface toward the injection hole, and the projection is formed to be smaller in a direction of fuel flow between seats than a radius of an upstream opening surface of the injection hole.
