Zusammenfassung:	Provided are a battery pack that has such superior impact strength as to prevent a slender connective arm from breaking on impact, and a method for manufacturing this battery pack. The battery pack includes a plurality of batteries (1) each including respective electrode terminals (1x, 1y) disposed in face-to-face relation, and lead plate (3) connecting each of the plurality of batteries (1). Lead plate (3) includes turnback part (33) and fixed piece (31) connected to electrode terminal (1x, 1y). Lead plate (3) also includes flat part (32) at each of ends of turnback part (33), and connective arm (34) that has a narrower width than fixed piece (31) and connects flat part (32) and fixed piece (31). Turnback part (33) includes bending part (37). Bending part (37) includes any one of through hole (37A) provided in turnback part (33), side notch (37B) where turnback part (33) has a narrower width, and thinned part (37C) that is a thinned part of turnback part (33).
