PROBLEM TO BE SOLVED: To provide a current detector which detects a current flowing through a conductor on a substrate with high accuracy.SOLUTION: A base part 10 formed of an insulation material is provided with a coil 20 and an electrification part 30. The coil 20 is configured of a first radial wiring 21, a second radial wiring 22, and a connection wiring 200 with a central angle formed in a circular arc shape of 180°. The electrification part 30 is provided in a radial direction of the coil 20, and configured of an abutting part 32 which can abut against a conductor 6 provided in a base plate 5 and a distribution part 31 connected to the abutting part 32. The distribution part 31 is located in the vicinity of the coil 20 as compared with the conductor 6. When the abutting part 32 abuts against the conductor 6, part of the current that flows through the conductor 6 flows through the vicinity of the coil 20. In this way, an induction electromotive force generated in the coil 20 according to a change of the current flowing through the conductor 6 becomes large. Consequently, the current flowing through the conductor 6 can be detected with high accuracy. |
