<P>PROBLEM TO BE SOLVED: To reduce noise occurring in an electric power transmission line connected to an electric circuit in an onboard power supply system. <P>SOLUTION: An onboard power supply system includes a positive electrode bus bar 30P and a negative electrode bus bar 30N which transmit electric power to an electric circuit unit. The positive electrode bus bar 30P and the negative electrode bus bar 30N include a flat plate opposing section where the bus bars are disposed in parallel with each other so that plate surfaces thereof face each other. The positive electrode bus bar 30P is arranged so that the upper plate surface faces the inner face of a unit case 26 and the lower plate surface faces the upper plate surface of the negative electrode bus bar 30N. The negative electrode bus bar 30N is arranged so that the lower plate surface faces the inner face of the unit case 26 and the upper plate surface faces the lower plate surface of the positive electrode bus bar 30P. <P>COPYRIGHT: (C)2012,JPO&INPIT |
