A fuel supply control device is provided in which a parallel flow path of an orifice and a pressurizing valve is used as a complex pressurizing valve for a fuel supply amount, and which controls a fuel supply pump on the basis of a pressure difference before and after the complex pressurizing valve that has been detected by a pressure difference meter. When the rotational speed of the fuel supply pump is below a predetermined threshold value, the fuel supply pump is controlled on the basis of a first fuel measurement amount, and the fuel supply pump is controlled on the basis of a second fuel measurement amount.
