Disclosed is a catalyst for producing ethylene oxide, which is excellent in catalyst selectivity and catalyst life (durability). The specific surface area is 0.5 to 1.3 m 2 / g, the Si content (SiO 2 conversion) is 0.1 to 5.0 mass%, and the Na content (Na 2 O conversion) is 0.00. A catalyst for producing ethylene oxide, comprising a support having a mass of 0.5 to 1.0% by mass carrying a catalyst component containing silver (Ag), cesium (Cs), rhenium (Re) and tungsten (W) or molybdenum (Mo). .
