ISOLATION TRANSFORMER AND METHOD FOR MANUFACTURING ISOLATION TRANSFORMER

WIPO Patent Application WO/2021/145203

A1

Provided are: an isolation transformer having stable electrical characteristics; and a method for manufacturing the isolation transformer.　An isolation transformer (50) comprises: a circuit board (40) in which a first through hole (50F) is formed; a first pattern (50B) disposed around the first through hole (50F); a second pattern (50C) disposed around the first through hole (50F) and insulated from the first pattern (50B); and a magnetic body section (50A) having a first magnetic body (50D) and a second magnetic body (50E). The second magnetic body (50E) is disposed so as to face one surface of the circuit board (40). The first magnetic body (50D) has a first insertion section (50G) at least partially inserted into the first through hole (50F). A first end section (50N) on one surface of the first insertion section (50G) is disposed so as to face the second magnetic body (50E). The external dimension of the second magnetic body (50E) in a first direction (Di) that extends along the one surface, is greater than the external dimension of the first end section (50N) in the first direction (Di).
