A method of manufacturing a valve element for a solenoid valve to open and close a valve seat, comprising the steps of; preparing a leaf spring including an outer peripheral ring section and a hub section having a central hole, forming a ring-shaped outer peripheral seal along the peripheral ring section, and preparing a movable core having a cup-shaped cross section and including a cylindrical section and an end wall section. The method further comprising, forming a valve seal on the end wall section by placing the movable core and the leaf spring in a mold and aligning and holding the leaf spring and the stepped section in contact with each other, and aligning a holder ring along an outer periphery of the movable core, and bringing the holder ring into engagement with the movable core, wherein the leaf spring and the movable core are rigidly secured to each other.
