ABSTRACT:
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.
