PROBLEM TO BE SOLVED: To provide a battery system which can achieve compaction and lightweight by reducing the influence of an inductance component, even if the length of wiring interconnecting a plurality of battery elements is lengthened.SOLUTION: A battery module 213 is constituted by interconnecting a plurality of battery cells 217-11 through 217-16 each having a rectangular parallelepiped shape. Bus bars W11, W12 (first current path) for interconnecting the battery cells 217-11 through 217-13 conductively in series, and bus bars W14, W15 (second current path) for interconnecting the battery cells 217-14 through 217-16 conductively in series are disposed while keeping a substantially predetermined interval from each other. Circulation directions of currents in the bus bars W11, W12 and W14, W15 are set in reverse direction from each other at a reversal part R1 consisting of a positive electrode terminal Tp14, a negative electrode terminal Tn13 and the bus bar W13. |
