Abstract
To suppress a temperature increase of a transformer. A transformer includes a core, a primary winding, and a secondary winding. The core includes a primary core and a secondary core disposed on a side of the primary core. The primary winding includes a first primary winding wound around the primary core and the second primary winding wound around the secondary core and electrically connected in series to the first primary winding. The first primary winding is disposed such that a direction of a magnetic flux on an inner peripheral side of the first primary winding induced by the first primary winding is opposite to a direction of the magnetic flux on the inner peripheral side of the second primary winding induced by the second primary winding. The secondary winding is wound such that a winding axial line of the first primary winding and a winding axial line of the second primary winding are formed on an inner peripheral side of the secondary winding.
