A fuel injector includes a tube member and a valve element to slide axially in the tube member. The valve element includes a center portion and a plurality of plate portions projecting radially from the center portion, and each including side surfaces extending axially; and a guide section including an outer portion defining a valve seat, and an inner portion which is located on a radial inner side of the outer portion, and which is formed with at least one injection hole. The guide section is arranged to divert the flow of the fuel conveyed along the plate portions, to a radial inward direction toward the injection hole.
