Zusammenfassung:	To provide a cathode active material that greatly increases the capacity of a battery when applied to a lithium ion battery.SOLUTION: A spinel-type lithium cobaltate is doped with chromium. Specifically, a cathode active material for a lithium ion battery has a spinel-type crystal phase containing lithium, cobalt, chromium, and oxygen, and has a composition represented by LiCoCrMO(M is at least one selected from Al and Mn, and 0.85≤x
