Abstract
Provided is a magnetic element, including: a coil assembly in which a coil is provided on an outer periphery of an inner core; and an outer peripheral core provided to cover an outer periphery of the coil assembly. The outer peripheral core has: an opening that allows the coil assembly to be inserted therein; and a fixing part configured to fix the coil assembly into the outer peripheral core. The coil is sealed by a sealing resin. A lid member is mounted to an opening of the outer peripheral core, and is configured to reduce a gap between the coil and the outer peripheral core in the opening so as to reduce a filling amount of the sealing resin.
