Abstract
A planar transformer includes: a primary side planar air core coil; a secondary side planar air core coil; a primary side planar core; and a secondary side planar core. The secondary side planar air core coil is arranged so as to be spaced from the primary side planar air core coil in the winding center axis direction of the primary side planar air core coil, the secondary side planar air core coil having a non-facing portion configured not to face the primary side planar air core coil in the winding center axis direction. The primary side planar core and the secondary side planar core are stacked on outer sides of the primary side planar air core coil and the secondary side planar air core coil in the directions of the winding center axes, respectively.
