A bar antenna includes a single body ferromagnetic substance core, a bobbin which accommodates the core in a hollow space and has a plurality of coil windings, a case in which is positioned the core and the bobbin, and a potting material in the case and/or the bobbin. The potting material isolates the core from temperature changes, humidity changes and vibration.

A compact-size variable resistance device has a terminal for electrical connection to an external device, a resistor that slidingly contacts with a brush, and connecting parts formed of an electro-conductive resin containing a thermoplastic resin. The electro-conductive resin connecting parts readily make reliable electrical interconnection of the terminal and the resistor when the connecting parts are joined by, for example, ultrasonic bonding.

A printed circuit board having electrical components connected thereto in spaced relation is coated with a resin material by immersion in a container of resin material. The flow of resin between the electrical devices and the circuit board is facilitated by the provision of holes through the circuit board in alignment with each electrical component so that the formation of blow-holes is prevented.
