Abstract:
1. A circuit board comprising: an insulating member having a plate shape, and including a through hole configured to allow a die punching tool to pass through the insulating member; a first circuit pattern and a second circuit pattern formed by die punching of a conductor having a plate shape in a manner that the first and second circuit patterns are coupled with each other by a first coupling section; wherein the first circuit pattern and the second circuit pattern are secured to a front surface of the insulating member by an adhesive, wherein the first coupling section faces the through hole of the insulating member a third circuit pattern secured to a back surface of the insulating member by an adhesive, and the first coupling section is configured to be removed in order to electrically isolate the first circuit pattern and the second circuit pattern from each other after the insulating member having the through hole is secured to the first circuit pattern and the second circuit pattern.
