The present invention can be used for an internal combustion engine having the principal parts thereof made of an aluminum alloy, and exhibits excellent productivity. Provided are a pressure ring, an internal combustion engine using the pressure ring, a wire stock for the pressure ring used for the internal combustion engine, and a method of manufacturing the wire stock for the pressure ring. The pressure ring is used for an internal combustion engine having the principal parts thereof made of an aluminum alloy wherein: a base material constituting a ring-shaped pressure ring body with an abutment part has a composition comprising, by mass%, C: 0.7-1.6%, Si: 0.6-1.2%, Mn: 0.3-0.7%, P: 0-0.04%, S: 0-0.09%, Ni: 0.3-0.6%, Cr: 7.5-9.0%, Mo: 0.7-1.0%, V: 0-0.5%, W: 0.2-0.5%, Cu: 0.2-0.6%, Al: 0.1-0.5%, Nb: 0.05-0.15%, and the balance Fe and incidental impurities; the base material has a Vickers hardness of 435 to 510; and a nitride layer is formed on the upper and lower faces of the pressure ring body.
