Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for producing a Co-Zr intermetallic compound sheet. SOLUTION: The method for producing a Co-Zr intermetallic compound is provided with a process where a Co-Zr ingot comprising 49 to 50.5at% Zr, and the balance Co with inevitable impurities is subjected to homogenizing heat treatment, is thereafter subjected to first hot rolling at 1,173 to 1,323 K, is subjected to second hot rolling at 773 to 1,073 K, is subjected to recrystallization heat treatment at 973 to 1,323 K, and is subsequently subjected to cold rolling.
