Abstract
A coupling capacitance estimation method includes arranging numerous input electrodes to respectively face first exposed end portions of numerous insulated wires exposed at one end of a multicore cable, arranging numerous output electrodes to respectively face second exposed end portions of the numerous insulated wires exposed at another end of the multicore cable, performing measurement of a voltage value of a measurement output signal that is output by capacitive coupling from the second exposed end portion through the output electrode when a measurement input signal is input by capacitive coupling from the input electrode to the first exposed end portion, with a plurality of predetermined different combinations of the input electrodes to input the measurement input signal and the output electrodes to output the measurement output signal, and based on the measured voltage values of a plurality of the measurement output signals, estimating respective coupling capacitances.
