Bus bar, bus bar module, and method of manufacturing bus bar

A bus bar used for electric connection, comprising:

• a laminated conductive wire, where two or more conductive wires, configured by one or a plurality of stripe conductors covered with an insulating film having been wound in a spiral form so as to be adjacent in a width direction of the stripe conductor, are configured in a flat plate form so that opposing surfaces of a wound interior are in proximity or in close contact are disposed side-by-side in a longitudinal direction of each, and overlaid and laminated so that an outer surface of each in the width direction face each other;
• and
• terminal parts, disposed on both ends of the laminated conductive wire and bonded to the two conductive wires,
• wherein the two conductive wires include
• a first conductive wire where one or a plurality of stripe conductors covered with an insulating film are wound in a spiral form so as to be adjacent in a width direction of the stripe conductor, and configured in a flat plate form so that opposing surfaces of a wound interior are in proximity or in close contact, and
• a second conductive wire where one or a plurality of stripe conductors covered with an insulating film are wound in a spiral form, in an opposite direction to the first conductive wire, so as to be adjacent in a width direction of the stripe conductor, and configured in a flat plate form so that opposing surfaces of a wound interior are in proximity or in close contact.
