PROBLEM TO BE SOLVED: To provide an electric power unit for a vehicle which is excellent in vehicle mountability and has a high cooling efficiency.SOLUTION: An electric power unit for a vehicle comprises a front module group cooling part 131 for cooling a front module group, and a middle module group cooling part 132 for cooling a middle module group. The front module group cooling part 131 and the middle module group cooling part 132 are connected in series. The front module group cooling part 131 and the middle module group cooling part 132 have plural cooling jackets 131a and cooling jackets 132a for cooling each battery module or two or more battery modules. The plural cooling jackets 131a are connected in series, and the plural cooling jackets 132a are connected in parallel.SELECTED DRAWING: Figure 4
