PROBLEM TO BE SOLVED: To provide an electric power generation controller for a vehicle capable of preferentially protecting extraneous surge voltages in a circuit in order of high priority when the difference in order of protection priority on the extraneous surge voltages is provided.SOLUTION: An electric power generation controller for a vehicle 1 includes: a plurality of external terminals; a plurality of surge protection circuits 170, 172, 174, 176, 178 which are provided corresponding to each of the plurality of external terminals and reduce the voltages of these external terminals when extraneous surge voltages are applied; and a plurality of circuits in which order of protection priority on the extraneous surge voltages is different and a power source circuit 100 or the like in order of high priority is arranged separated from the surge protection circuit 170 or the like. |
