An ether compound is advantageously produced by an ether exchange reaction of a different ether compound and a hydroxy group containing compound in the presence of a heteropoly acid or an acidic salt thereof as the catalyst. The catalyst is novel and is extremely effective to the present process and brings about less by-products compared to other processes or other catalysts.
