Abstract

A transformer device includes: a transformer that includes a magnetic body core and a winding; a case that houses the transformer; an external terminal that is provided in the case; a relay section that is provided in the case and to which an end portion of the winding of the transformer is connected; and a conducting wire of which one end is wound around the external terminal and bonded thereto, and another end is connected to the relay section.

Claims (16)

1. A transformer device comprising:

a transformer that includes a magnetic body core and a winding;

a case that houses the transformer;

an external terminal that is provided in the case;

a relay section that is provided in the case and to which an end portion of the winding of the transformer is connected; and

a conducting wire of which one end is wound around the external terminal and bonded thereto, and another end is connected to the relay section,

wherein the conducting wire is formed by an extending portion of the winding of the transformer, and
