PROBLEM TO BE SOLVED: To provide a positive electrode for a lithium secondary battery capable of achieving both high capacity, high output and long life of the lithium secondary battery, and a lithium secondary battery using the positive electrode for lithium secondary battery. A positive electrode containing a compound capable of inserting and extracting lithium as an active material, and containing a conductive agent and a binder, wherein the specific surface area of the active material is A (m 2 / g), The content ratio of the active material is Bwt%, the specific surface area of the conductive material is C (m 2 / g), the content ratio of the conductive material in the electrode is Dwt%, and the active material exposure ratio of the bent cross section of the positive electrode is E (%). When it does, the positive electrode for lithium secondary batteries which satisfy | fills the following formula | equation (1). E <50 × (A × B + 0.05 × C × D) / (A × B + 0.1 × C × D) (1) [Selection figure] None |
