Abstract
Provided is a fuel injection valve capable of quickly stopping a position of a movable element at a predetermined position after closing a valve while reducing an impact force of a valve body. Therefore, a valve bodyincludes a sleeve. A first movable core(first movable element) lifts the valve bodyby the attractive force of a magnetic core. A second movable core(second movable element) further lifts the valve bodyby the attractive force of the magnetic coreafter the first movable core(first movable element) lifts the valve body. After the valve bodyis seated on the seat memberand the second movable core(second movable element) is separated from the sleeve, a bottom surfaceof the first movable core(first movable element) collides with a storage bottom surface(collision receiving portion).
