A low-pressure fuel supplying system (5), a fuel supply control system (6) and a high-pressure fuel discharging system (3) are independently provided as separate pieces, and the low-pressure fuel supplying system (5), the fuel supply control system (7) and the high-pressure fuel discharging system (3) are connected by a fuel pipe. As the high-pressure fuel discharging system (3) is small, relative to a fuel injection pump, it is easier to provide a space for mounting the high-pressure fuel discharging system (3) in the vicinity of the engine. On the other hand, as the low-pressure fuel supplying system (5) and the fuel supply control system (7) have no restriction regarding mounting position, they can be mounted in any empty space in an engine room. Accordingly, the high-pressure fuel supplying apparatus has enhanced mountability on a vehicle.
