ABSTRACT:
An electronic component includes a plurality of current path pairs which are arranged on the same circle. Currents flow through first current paths forming respective current path pairs in first directions, and currents flow through second current paths in second directions opposite to the first directions. The first current paths and the second current paths are arranged alternately. Therefore, magnetic fields generated by the currents in the first directions and magnetic fields generated by the currents in the second directions are canceled by each other, whereby residual inductance becomes small. In the case where the electronic component is a cable, the current paths are conductors buried in an insulation member. In the case where the electronic component is a capacitor, at least one of the current paths forming the pair is a capacitor unit.
