Abstract
In a linear solenoid valve, a coil wound on a bobbin is disposed radially outside a first core and a second core of that configure a part of a core segment, and a cover portion is formed by filling the outer periphery of the coil with a resin material so that the coil and the core segment are integrally molded together. The first core includes a small diameter portion having an outside diameter rsmaller than an outside diameter rof an outer tubular portion that is part of the second core and that is opposed to the coil, and a large diameter portion that has an outside diameter rlarger than that of the small diameter portion. A space between the small diameter portion and the bobbin makes it less likely that the first core is pressed radially inward via the bobbin during formation of the cover portion.
