Converters that convert radio waves in the UHF band to VHF band usually use a shield case, which is made of a metal plate and divided by shield plates to form several small chambers. A circuit board incorporating components such as capacitors, resistors, transistors, or thick film circuit elements that integrate these into an integrated circuit is housed, and these circuit boards are electrically connected with conductive wires that pass through the S shield plate, or the case is closed. It has a structure in which it is electrically connected to the outside through a penetrating terminal. The circuit board was attached to the case by soldering it to a metal case or terminals set up on the case, or by screwing it directly to the case.
