由此，能量密度有可能降低
Benefits of technology
[0022]另外，在本发明的固体电池中，在电极层中，集电体部分具有相对于活性物质部分相对较小的活性物质密度，因此能够抑制电极活性物质的存在部和非存在部对置的区域中的离子的扩散及过剩的离子供给。因此，能够进一步提高充放电中的电极层内的反应均匀性。

Abstract
Provided is a solid-state battery having a solid-state battery laminate in which a positive electrode layer, a negative electrode layer, and a solid electrolyte layer interposed between the positive electrode layer and the negative electrode layer are laminated, the solid-state battery having external terminals of positive and negative electrode terminals respectively provided on opposite side surfaces of the solid-state battery laminate. In the solid-state battery, the electrode layers of the positive electrode layer and the negative electrode layer have an active material portion containing an active material for the electrode layer and a current collector portion having a relatively small active material density relative to the active material portion, and the solid-state battery has an end surface current collection structure in which the current collector portion provided on an end surface of the active material portion collects current.
