PROBLEM TO BE SOLVED: To provide an in-vehicle voltage generating device capable of preventing heat generated due to voltage generation from having an influence on the operations of an electronic apparatus around the voltage generating device. SOLUTION: The microcomputer 12 of the voltage generating device calculates the driving interval T of a fuel injection valve. When the driving interval T is a specified time T1 or shorter, a first maximum energized current value and a first minimum energized current value are output to a driver 14 as a maximum energized current set value Imax and a minimum energized current set value Imin (S100 to S120). On the other hand, when the driving interval T is longer than the specified time T1, a second maximum energized current value and a second minimum energized current value are output to the driver 14 as the maximum energized current set value Imax and the minimum energized current set value Imin (S140).
