PROBLEM TO BE SOLVED: To obtain a metal-based catalyst which hardly causes peeling of the catalyst even when the catalyst is used in a fluid such as flowing water or in such a state that the carriers which fix the catalyst are rubbed with one another, by mixing the catalyst in a thermosetting resin, hardening and carbonizing the thermosetting resin. SOLUTION: This catalyst consisting of a thermosetting resin such as a phenol resin, furan resin, epoxy resin, thermosetting polyimide and metals such as nickel, copper, iron, zinc, chromium, cobalt, manganese and magnesium or metal oxides such as titanium oxide and iron oxide, or consisting of a mixture of the resin and a catalyst precursor is heated at >500 deg.C in a nonoxidizing atmosphere to harden and carbonize the thermosetting resin. The metals or metal compds. are deposited on the carbonized material. Thereby, even when the catalyst is used in a fluid such as flowing water or in such a state that the carriers which fix the catalyst are rubbed with one another, the metal-based catalyst hardly causes peeling of the catalyst.
