Abstract:
A battery (1) comprises: a power generation element (5) obtained by superposing a plurality of current collectors and a plurality of battery cells (100) each comprising an electrode layer (110), a counter-electrode layer (120), and a solid-electrolyte layer (130); a plurality of electroconductive pieces (20); and a counter-electrode insulating layer (31). The plurality of current collectors comprise electrode current collectors (140) and counter-electrode current collectors (150). The plurality of electroconductive pieces (20) include first-electrode electroconductive pieces (21), which are connected to the electrode current collectors (140) on a side surface (11) of the power generation element (5). On the side surface (11), the counter-electrode insulating layer (31) covers both at least some of the counter-electrode current collectors (150) and the electroconductive pieces (20) excluding the first-electrode electroconductive pieces (21).
