摘要：PROBLEM TO BE SOLVED: To provide a closely sealed secondary battery. SOLUTION: This secondary battery comprises an electrode body 2 and external films 3 for wrapping the electrode body 2. Two sheets of upper and lower external films 3 are overlapped with each other and the edge parts thereof are joined with each other to seal the electrode body 2. The electrode body 2 comprises an external terminal 4 with projected parts 41. The projected parts 41 are projected to the outside of the battery through the external films 3. Then, sealing part 5 is circumferentially provided on the projected parts 41. COPYRIGHT: (C)2004,JPO
