Abstract of the Disclosure A silver-deposited catalyst for production of ethylene oxide by oxidizing ethylene, having high selec- tivity and long life, is provided by this invention. The catalyst is characterized by a combination of (a) catalyst ingredients comprising silver and a cation component selected at least from sodium, potassium, rubidium and cesium, and (b) a carrier composed mainly of alpha- alumina, said carrier having a surface area of 0.6 to 2 m2/g, a water absorption of 20 to 50%, a silica content of 0.5 to 12% by weight, a silica content, per m2/g of sur- face area, of 0.5 to 12, preferably 1 to 8, and a sodium content of 0.08 to 2% by weight.
