PROBLEM TO BE SOLVED: To provide a jumper bus bar of a printed board assembly which allows electrification of a large current such as of several tens of amperes, is hard to be induction heated by a leaking magnetic flux, and is excellent in heat dissipation property.SOLUTION: A jumper bus bar is made of a conductive member which is implemented on a printed board containing a front surface, a rear surface, and a plurality through holes. It includes a body part which is plate-like extending in length direction and has a plurality of heat radiation fins, and a plurality of lead parts extending toward the printed board. When the plurality of lead parts are inserted into the through holes, each of lead parts abuts with an inner wall of the through hole that has a circular cross section, on the front surface of the printed board. A thickness in the direction vertical to the length direction is thinner at the rear surface than at the front surface of the printed board. |
