Abstract
A reactor including: a coil having a winding portion; a magnetic core having a plurality of core pieces; and an inner interposed member interposed between the winding portion and an inner core portion of the magnetic core. An inner resin portion fills an internal space of the winding portion, the inner interposed member includes core holding portions holding the core pieces to be decentered relative to the inner interposed member when seen in the axial direction of the winding portion, a separation distance between the inner circumferential surface of the winding portion and the outer circumferential surface of the inner interposed member on a displacement direction side is longer than a separation distance between the inner circumferential surface of the winding portion and the outer circumferential surface of the inner interposed member on the side that is opposite the displacement direction side.
