Abstract
A magnetic balance type current sensor includes a plurality of coils and a magnetic detection element whose characteristics change depending on a magnetic field induced by a current to be measured. Each of the plurality of coils includes a coil wire section disposed on a surface located away from a reference plane, a lead wire section connected to the coil wire section, and two electrode sections connected individually to the coil wire section and to the lead wire section. Each of the plurality of coils is capable of generating a canceling magnetic field when a feedback current is passed by using the electrode sections. The lead wire sections and the coil wire sections have crossing portions in which the lead wire sections and the coil wire sections are layered with an insulating section interposed so as to overlap each other in a winding axis direction of the coil wire sections.
