By reacting a mixture of a halogenoalkyl group-bearing organosilicon compound and sulfur with an aqueous solution or water dispersion of an ammonium or alkali metal sulfide or a hydrate thereof in the presence of a phase transfer catalyst, a sulfide chain-bearing organosilicon compound having the average compositional formula (2): <?in-line-formulae description="In-line Formulae" end="lead"?>(R<SUP>1</SUP>O)<SUB>(3-p)</SUB>(R<SUP>2</SUP>)<SUB>p</SUB>Si-R<SUP>3</SUP>-S<SUB>m</SUB>-R<SUP>3</SUP>-Si(OR<SUP>1</SUP>)<SUB>(3-p)</SUB>(R<SUP>2</SUP>)<SUB>p</SUB> (2) <?in-line-formulae description="In-line Formulae" end="tail"?> wherein m has an average value of 2<=m<=6 is obtained in high yields and at a low cost with minimized formation of a monosulfide-bearing organosilicon compound.
