Abstract
A nozzle holder includes a support portion, which supports a downstream end surface of a planar wall of an injection hole plate. The injection hole plate provided with injection holes is welded to one of the valve body and the nozzle holder. The planar wall may be curved and may be thus convex in an upstream direction toward a downstream end opening such that the planar wall is urged against a peripheral edge of the downstream end opening of the valve body. The planar wall may include a reinforcing rib located radially outward of the injection hole.
