<P>PROBLEM TO BE SOLVED: To prevent malfunction of an electronic component resulting from high voltage applied from a bus bar, in a current detection device for detecting a current flowing in the bus bar, while downsizing the current detection device. <P>SOLUTION: The current detection device 1 includes: an electronic substrate 50 on which a circuit for processing a detection signal of a hole element 20 disposed in a gap portion 11 of a magnetic material core 10 is mounted; and a spring member, such as a coil spring 52, composed of a conductor electrically connected to a ground pattern of the electronic substrate 50, supported by the electronic substrate 50, and abutting on the magnetic material core 10. The magnetic material core 10, a current detecting bus bar 30, and the electronic substrate 50 with the hole element 20 mounted thereon are held in a constant positional relation by an insulating housing 40. <P>COPYRIGHT: (C)2012,JPO&INPIT |
