PROBLEM TO BE SOLVED: To provide a polymer lithium secondary battery with a reduced contact resistance of a positive electrode, and an improved rate characteristic. SOLUTION: This polymer lithium secondary battery is provided with a collector 4 and a positive electrode 1 including a positive electrode layer 6 formed on one or both surfaces of the collector 4 through a conductive adhesion auxiliary layer 5. The conductive adhesion auxiliary layer 5 includes at least one type of copolymer selected from copolymer of olefin and monomer represented by a formula, copolymer of fluoromonomer and the monomer, and copolymer of one type of monomer selected from olefin and fluoromonomer and the monomer, and a conductive material. |
