CURRENT DETECTION APPARATUS

摘要

PROBLEM TO BE SOLVED: To prevent an electronic component from falling into a failure by a high voltage applied from a busbar and to attain reduction in size compatibly in a current detection apparatus for detecting a current flowing to the busbar.

SOLUTION: A current detection apparatus 1 includes a housing 40 maintaining components of a magnetic substance core 10, a current detection busbar 30 and a hole element 20 disposed in a gap part 11 of the magnetic substance core 10 in a fixed positional relationship. The housing 40 comprises a cover member 42 of a conductor and a main body case 41 of an insulator which are combined with each other to hold the components. The cover member 42 of the conductor is a heat radiating part in contact with the current detection busbar 30.
