An episulfide compound useful as a starting material for optical materials that have a high refractive index and a high Abbe's number is provided. A method for producing the same and an optical product made with the same are also provided. The episulfide compound may be represented by the general formula (1): wherein EP represents and n is an integer of from 0 to 2. A method for producing the episulfide compound represented by the general formula (1) may involve reacting a mercapto group-containing episulfide compound with 2,4,6-trimethylene-1,3,5-trithiane.
