A diesel pump having enhanced durability in a high pressure environment, capable of being produced at high productivity, and low in cost. The diesel pump (1) is provided with a cylinder (5) formed in a pump housing (3), a plunger (7) reciprocatably provided in the cylinder (5), and a drive mechanism (9) for driving the plunger (5). The cylinder (5) is a separate part from the pump housing (3) and is mounted in the pump housing (3). The cylinder (5) consists of sulfur-less alloy steel. The cylinder (5) is a tubular part and may be press-fitted in the pump housing (3). The front end of an outlet joint (41) reaches the cylinder (5), and a fuel discharge route directly connects to the outlet joint (41) from the cylinder (5) without passing through the pump housing (3).
