Claims

[Scope of utility model registration request]

A small multiple variable capacitor comprising a plurality of variable capacitor sections including a small capacitance variable capacitor section such as UHF is mounted on a front end board that constitutes a receiving circuit related to the small capacitance variable capacitor section, and the front end board is attached to another. When the variable condenser section is housed in a shield case to be shielded from receiving circuits, etc. related to the variable condenser section, a part of the shield case is shaped to follow the side surface of the variable condenser, and a part of the shield case is shaped to follow the side surface of the small capacity variable condenser section of the variable condenser. The front end of the Chuna is characterized by being configured to act as a shield plate.
