VARIABLE RESISTOR

[PROBLEMS] To suppress power consumption in a resistor element in a variable resistor during a non-operation state. [MEANS FOR SOLVING PROBLEMS] On a substrate surface of a second insulating substrate (17), a first resistor (11) and a second resistor (12) are arranged side by side in an insulating state. On a first insulating substrate (18) arranged to oppose to the second insulating substrate (17), a conductor (13) is formed on the surface opposing to the second insulating substrate (17). The second insulating substrate (17) and the first insulating substrate (18) are formed by flexible substrates so that the first resistor (11), the second resistor (12), and the conductor (13) may be brought into a pressed contact. Voltage is applied from a voltage output unit (21) across a first voltage application unit (14) of the first resistor (11) and a voltage application unit (15) of the second resistor (12). When in a non-pressed state, i.e., in a wait state, the first resistor (11) and the second resistor (12) are not electrically connected, thereby causing no power consumption. ® KIPO & WIPO 2008
