摘要： The alternating current detection coil is a toroidal coil, and comprises plural radial-line conductors which are formed on a front face and a rear face of a substrate, conductive connection parts and conductive through-holes which connect electrically each end of radial-line conductors, wherein plural winding turns are consecutively formed by a connection of each radial-line conductor on the front face and the rear face respectively, the winding turns comprise a forward coil and a backward coil, and each shape on the front face and the rear face of the radial-line conductors and the conductive connection parts are identical with each other. Consequently, when seen from a thickness direction of the substrate, areas of the forward coil and the backward coil are equal to each other, and an external magnetic field, which does not need to be detected, can be canceled each other by the forward coil and the backward coil, then a current detection accuracy can be improved.
