PROBLEM TO BE SOLVED: To provide a small and highly releiable solenoid valve by improving productivity by reducing the number of part items. SOLUTION: This solenoid valve having a housing 6, a coil 5, a bobbin 7, a stator 1, a movable iron core 2 and a fixed iron core 4, arranging a first seat part 2a on an upper surface of the movable iron core and a second seat part 2b on a bottom surface and moving the movable iron core by carrying an electric current to the coil, is featured by arranging a passage on a side surface of the movable iron core so as to penetrate up to the bottom surface from the upper surface in the shaft direction.
