Abstract

An injection hole body has multiple injection holes for injecting fuel. A valve body is unseated from and seated on a seating surface of the injection hole body. The injection hole body and the valve body form a specific space therebetween to communicate with inflow ports of the injection holes. A virtual region is surrounded by multiple straight lines. The straight lines connect portions of peripheral edges of the inflow ports, which are closest to a center axis of the valve body in the radial direction. A center volume is formed by extending the virtual region from the injection hole body toward the valve body along the center axis. A total injection hole volume is a total volume of the injection holes. The total injection hole volume is larger than the center volume in a state where the valve body is seated on the seating surface.
