Abstract
A metal oxide-coated positive electrode active material (1) having a metal oxide coat layer (3) that entirely coats a surface of a positive electrode active material (2) has pores (4) which are connected from the surface of the positive electrode active material (2) to a surface of the metal oxide coat layer (3) and through which lithium ions are allowed to move. The pores are present in the metal oxide coat layer (3) entirely over the surface thereof.
