A positive electrode for a lithium secondary battery provided by the present invention includes a positive electrode active material layer having a particulate positive electrode active material constituted by a composite oxide containing lithium and at least one type of transition metal element, and at least one type of binding material constituted by a polymer compound having at least one functional group, and a conductive carbonaceous coating film is formed on a surface of the positive electrode active material. Further, the polymer compound constituting the binding material is molecularly bound to carbon atoms constituting the carbonaceous coating film of at least a part of the positive electrode active material, whereby a composite compound is formed from the polymer compound molecularly bound to the carbon atoms and a carbon network constituting the carbonaceous coating film containing the carbon atoms.
