A displacement-electric signal converter having a pair of displacement detecting elements the impedances of which vary in accordance with a displacement, a rectifier including a bridge circuit, first and second capacitors, an oscillator for supplying AC current to the displacement detecting elements, a circuit for controlling voltage for the oscillator, and amplifier for amplifying current flowing through the second capacitor. In this case, the output signal is supplied to a load through a transmission line of a DC electric power source for the amplifier.
