Abstract
A conductive path with noise filter that enables an effective reduction in a surge noise in a specific frequency band is provided. A conductive path with noise filter includes conductive path main bodies, insulating layers that respectively surround the conductive path main bodies, conductive layers that are respectively provided to correspond to the conductive path main bodies with the insulating layers being sandwiched between the conductive layers and the conductive path main bodies and that respectively form capacitors in combination with the conductive path main bodies, and inductors connected to the conductive layers.
