PROBLEM TO BE SOLVED: To provide a battery in which a tab of electrically conductive material of an electrode unit can be fixed without corroding while excellently hermetically sealed by a coating body, and excellently connected to a positive electrode terminal or a negative electrode terminal.SOLUTION: A battery cell 1 includes: plural electrode units 8 each comprising a conductive material 82 having electrode materials 80, 81, and tabs 82a; other electrode units; and an outer packaging bag 2 having an adhesive portion 23 which covers these electrode units, and formed by sticking the outer peripheral edge portions thereof in an overlapping manner. The tab 82a is coated by coating portions 84g, 84h of s sealant 84, and the coating portions 84g, 84h are stuck while pinched by an adhesive portion 23a as a part of the adhesive portion 23. The tabs 82a protrude from the tip portions of the coating portions 84g, 84h, and are overlapped with one another and connected to a negative electrode terminal 4.SELECTED DRAWING: Figure 4 |
