PROBLEM TO BE SOLVED: To provide a polymer electrolyte secondary battery which is easy to assemble a pack battery by embedding positive and negative terminals in a frame body for housing a polymer electrolyte unit cell comprising a positive electrode layer, a negative electrode layer, and a polymer electrolyte layer interposed between both electrode layers. SOLUTION: A positive electrode layer containing an active material, a nonaqueous electrolyte, and a polymer which holds the nonaqueous electrolyte is stacked on a current collector to obtain a positive electrode. A negative electrode layer containing a carbon material capable of absorbing/releasing a lithium ion and holding the nonaqueous electrolyte is stacked on a current collector to obtain a negative electrode layer. A solid polymer electrolyte layer containing the nonaqueous electrolyte and a polymer for holding the nonaqueous electrolyte is interposed between the positive electrode layer and the negative electrode layer to obtain a polymer electrolyte unit cell 2. The polymer electrolyte unit cell 2 is housed in a frame body 8 made of an insulating material, and sealed with upper and lower covers 13, 14. Socket type terminals 9, 10 electrically connected to the positive and negative current collectors through lead wires 11, 12 are inserted from its one side into the frame body 8 and embedded. |
