摘要：
A positive active material according to the present invention used in a nonaqueous secondary battery, includes a lithium-containing transition metal oxide containing manganese, as a crystal structure of a main crystalline phase, and a sub oxide and tin (IV) oxide, each of which having an oxygen arrangement identical to that of the lithium-containing transition metal oxide however has a different element composition, the sub oxide and tin (IV) oxide being included in a state in which presence of the sub oxide and tin (IV) oxide is confirmable by diffractometry.
