とする平衡調整用可変抵抗器。A resistor is connected to extend between the pair of electrodes, and the resistor is connected so that a slider with two contact parts that can contact both ends simultaneously slides along this resistor. In the balanced adjustment variable resistor, the resistor has low resistance parts near the electrodes on both sides, and the resistance value per unit area between these low resistance parts is higher than that of the low resistance parts. The high resistance parts are selected such that the maximum power consumption per unit area of these low resistance parts and the maximum power consumption per unit area of the high resistance parts are selected to be equal to S.
