Each of the injection holes has an inclined angle with respect to a center line of an injection valve main body as well as the inclined angle of each of the injection holes is provided with a predetermined offset amount with respect to a target inclination angle of a center of gravity position of each of the injected fuel sprays. The predetermined offset amount is set based on a correction amount for correcting positional drift with respect to the target direction of the center of gravity position of the fuel spray.
