The present invention relates to a process for producing a pyridylethylthio compound which is improved in yield of the pyridylethylthio compound. In a process for producing a pyridylethylthio compound by reacting vinyl pyridine with a sulfur-containing compound, vinyl pyridine used contains a compound represented by the general formula (1):
(wherein R
1
and R
2
are any of combination of isopropenyl group and a hydrogen atom, combination of 1-propenyl group and a hydrogen atom, combination of 2-propenyl group and a hydrogen atom, and combination of methyl group and vinyl group),
in an amount of not more than 4% by weight.
