Abstract
A current detector that detects, based on output signals of N coreless current sensors, where N is a natural number of 3 or more, currents flowing in N conductors in a circuit connected so that the sum of the currents flowing in the N conductors becomes zero. The current detector has a signal-current correlation acquiring section that acquires a signal-current correlation representing a correlation between the output signals of the N coreless current sensors and the currents flowing in the N conductors. Furthermore, a current calculating section that calculates the currents flowing in the N conductors based on the output signals of all the N coreless current sensors by using the signal-current correlation.
