PROBLEM TO BE SOLVED: To manufacture a polysulfide silane having a short polysulfide chain in high yield at a low cost. SOLUTION: A method for manufacturing a sulfide chain-containing organosilicon compound of formula (3) by reacting a sulfide chain-containing organosilicon compound of formula (1), an alkali metal or an alkaline earth metal, and a halogenoalkyl group-containing organosilicon compound of the formula (2), and optionally sulfur with each other. (R<1> O)(3-p) (R<2> )p SiR<3> Sm R<3> Si(OR<1> )(3-p) (R<2> )p (1) (R<1> O)(3-p) (R<2> )p SiR<3> X (2) (R<1> O)(3-p) (R<2> )p SiR<3> Sn R<3> Si(OR<1> )(3-p) (R<2> )p (3) (wherein, R<1> and R<2> are each a monovalent hydrocarbon group; R<3> is a divalent hydrocarbon group; X is a halogen atom; 2<m<=6, 2<n<=6 and m>n; and p is 0, 1 or 2).
