<P>PROBLEM TO BE SOLVED: To reduce decrease in current detection sensitivity while suppressing influences of unnecessary external magnetic field and external electric field. <P>SOLUTION: A current detector 10 includes a coil 12 that is formed in an annular shape and detects current flowing through a conductor that penetrates the coil, and a shield part 13 covering the coil 12. Part of the shield part 13 covering the inner part of the coil 12 is provided with a slit 13a annularly extending along the coil 12 and communicating the coil 12 with the outside. <P>COPYRIGHT: (C)2013,JPO&INPIT |
