PURPOSE:To obtain stability of atomization in every time, by providing a guide member in a stay connected with a valve unit and slidably moving the guide member along the peripheral surface of a fixed iron core so that a movable iron core can be prevented from tilting. CONSTITUTION:When a valve is assembled, parallelness of a movable iron core 15 with a spacer 9 is not maintained, but the movable iron core 15, if it is once attracted to the side of a fixed iron core 4, collides against the spacer 9 stopping in a valve opening position. Here the movable iron core 15 is placed in a closely attached condition (parallel) with the spacer 9 because moment by impact force is set larger than the moment by friction. While a guide member 41, provided in a stay 16c mounted to the upper part of a valve unit 16, moves sliding on the internal peripheral surface of a center axis cavity part of the fixed iron core 4, and the injection valve, in which the valve unit 16 can be slided in the axial direction with no change of rotation, maintains the parallelness by friction force acting between the movable iron core 15 and the valve unit 16. Accordingly, the movable iron core 15 is placed always in parallel with the fixed iron core 4.
