PROBLEM TO BE SOLVED: To minimize decrease in production efficiency of an electrode assembly concerning inspection of lamination deviation thereof.SOLUTION: A first separator 31 and a second separator 32 have a first protrusion 331 and a second protrusion 332 where outer edges 231a, 232a are protruding, respectively, from four sides 122a, 122b, 122c, 122d of a positive electrode 12. The first protrusion 331 and second protrusion 332 have a joint 40 part. A negative electrode 13 has a protrusion 132 of such a shape as the outer edge 131a protrudes from the four sides 122a, 122b, 122c, 122d, respectively. The first separator 31, second separator 32 and the negative electrode 13 have first holes 132a, 331a, 332a and second holes 132b, 331b, 332b at positions overlapping when they are laminated. |
