PROBLEM TO BE SOLVED : To provide a sulfur trioxide decomposition catalyst, particularly, a sulfur trioxide decomposition catalyst capable of lowering the temperature required when producing hydrogen by an I-S cycle process. SOLUTION : The sulfur trioxide decomposition catalyst comprises a composite oxide of vanadium and at least one metal selected from the group consisting of transition metal and rare earth elements. Also, a sulfur dioxide production process comprises decomposing sulfur trioxide into sulfur dioxide and oxygen by using the sulfur trioxide decomposition catalyst. Furthermore, a hydrogen production process, wherein the reaction of decomposing sulfur trioxide into sulfur dioxide and oxygen is performed by the sulfur dioxide production process in the I-S cycle process, is disclosed.
