Abstract: An inductor includes a base body including a coil conductor and a core in which the coil conductor is embedded. The coil conductor includes a wound band-shaped conductive wire, and the core contains magnetic particles and a resin. The band-shaped conductive wire has a cross-sectional shape including principal faces that are parallel to each other and end faces that connect the principal faces to each other.
