摘要：
A cathode contains: a lithium cobalt composite oxide expressed by LixCoaM1bM2cO2, where M1 denotes the first element; M2 indicates the second element; x, a, b, and c are set to values within ranges of 0.9≦x≦1.1, 0.9≦a≦1, 0.001≦b≦0.05, and 0.001≦c≦0.05; and a+b+c=1; a first sub-component element of at least one kind selected from a group containing Ti, Zr, and Hf, and a second sub-component element of at least one kind selected from a group containing Si, Ge, and Sn. 0.01 mol %≦(content of the first sub-component element)≦10 mol % as a ratio to cobalt in the lithium cobalt composite oxide. 0.01 mol %≦(content of the second sub-component element)≦10 mol % as a ratio to cobalt in the lithium cobalt composite oxide.
