To provide a transformer configuration in which a turn ratio can be freely changed, ex post facto, in accordance to required specifications from a user.
A transformer 1 includes a primary winding 30 serving as a primary winding body, a secondary winding 25 serving as a secondary winding body, a base 2 on which a winding set-up 45 is mounted as composed of a combination of the primary winding 30 and the secondary winding 25, a connecting metal 40 attached to the base 2, and a core 102 serving as a core component formed from a magnetic component. In the transformer 1, the number of turns of an entire secondary winding 25, formed by a plurality of secondary windings 25 that are divided by one to several turns being connected by the connecting metal 40, is the number of turns of the secondary end. The number of turns of the entire secondary winding 25 can be freely changed as required merely by the connecting metal 40, provided in advance to allow various connection configurations.
