PROBLEM TO BE SOLVED: To provide a method of easily drawing around a wiring in a battery pack and fixing a wire rod securely. SOLUTION: The electrode tab 12 is provided with a rectangular base part 21 for welding and connecting electrode terminals of a plurality of battery cells and an extension part 22 extending from the periphery of the base part 21. The extension part 22 is provided so as to extend from a long side of the base part 21 to the short length direction, and is bent at the root of the extension part 22, and is arranged in a space formed between two adjoining battery cells. Furthermore, the extension part 22 has a projection part 26 in the central part in longitudinal direction and connecting parts at the both sides of the projection part. Furthermore, a through hole 24 which penetrates the projection part 26 from the root of the extension part 22 toward the tip direction is formed. The projection part 26 is bent in a dog-leg shape so that, for example, the central part may protrude toward the front surface. The connecting part can be soldered with a wire rod at the time of wiring. The through hole can fix the wire rod by passing the wire rod. COPYRIGHT: (C)2008,JPO&INPIT
