The present invention provides a dialkyl polysulfide which can be suitably used as an extreme pressure additive that can be added to a lubricant in a wide range of amounts, that enables effective formation of a film of a metal sulfide on a metal surface, and that is less likely to cause corrosion of the metal surface. In particular, provided is a dialkyl polysulfide containing compounds represented by General Formula (1) (where R.sup.1 and R.sup.2 each represent an alkyl group, and n is an integer from 1 to 6), wherein the total content of a compound in which n in General Formula (1) is 2 and a compound in which n in General Formula (1) is 3 is in the range of 80 to 100 mass % relative to the entire amount of the compounds represented by General Formula (1).
