In a solenoid valve, for preventing an elastic sheet used in a valve portion from being damaged by high-pressure gas flow, and without a seal in a wiring portion connected to a coil preventing pressure leakage from the wiring portion difficult to be sealed, particularly in a solenoid valve used for distribution control of high-pressure gas, a valve body is made of an inelastic material and dome-shaped, and a sheet surface facing the valve body is divided in a radial direction into an inelastic sheet surface closer to an axis of the valve body in a radial direction, and an elastic sheet surface far from the axis. The former is inclined to the valve body at a predetermined angle .theta.1 to a line orthogonal to the axis of the valve body. The latter is inclined at an angle 92 larger than the angle .theta.1 of the inelastic sheet surface. An elastic sheet surface in a boundary portion between the farmer and the latter is set on the same position as or lower than the inelastic sheet surface.
