The invention relates to a copper-based catalyst with high activity and a long catalyst life and to a method of producing the catalyst. This catalyst essentially comprises copper oxide, zinc oxide, aluminum oxide, and silicon oxide and optionally containing zirconium oxide, gallium oxide, and palladium oxide, wherein with the total weight of the catalyst being taken as 100%, the above oxides account for, in the order mentioned, 20-60 weight %, 10-50 weight %, 2-10 weight %, 0.3-0.9 weight %, 0-40 weight %, 0-10 weight %, and 0-10 weight %, respectively, and the silicon oxide mentioned above has been derived from colloidal silica or dissolved silica in water, which catalyst has been subjected to calcination at 480-690.degree. C.
