Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a current detection apparatus which is capable of detecting a current flowing to a switching element without being expanded in size and while suppressing a power loss.SOLUTION: A current detection apparatus 10 is applied to an electric circuit having a switching element 42 in which a bead core 21 is mounted for suppressing electric noise. A lead wire 22 is wound around the bead core 21. A signal generator 30 outputs a signal (value) correlated to a current of the switching element 42 in which the bead core 21 is mounted, on the basis of a current flowing to the lead wire 22.
