Abstract
A needle has a large-diameter portion, an outer diameter of which is larger than that of a shaft portion of the needle. A needle-side tapered surface is formed at the large-diameter portion on a valve closing side thereof, wherein the needle-side tapered surface is inclined by a needle angle with respect to a center axis of the needle. A core-side tapered surface is formed at a movable core, wherein the core-side tapered surface is inclined by a core angle with respect to the center axis of the needle. The needle and the movable core are brought into contact with each other via the needle-side and the core-side tapered surfaces. The needle angle and the core angle are made to be equal to each other.
