ABSTRACT:
A current detection equipment comprises a first coil and a second coil connected in series with the first coil. The current detection equipment is capable of detecting a current flowing through an object which is provided between the first and second coils or provided in a vicinity of the first or second coil. Each of the first and second coils having first conductive patterns provided on a surface of a substrate, a second conductive patterns provided on a back of the substrate and connecting parts which connect the first and second conductive patterns. A semiconductor device including the current detection equipment to measure the current flowing in a semiconductor element is also proposed.
