Abstract:
1. A secondary battery, comprising: a first electrode layer; a second electrode layer; and an electrolyte layer provided between the first and second electrode layers, the electrolyte layer including electrolyte particles, wherein at least one of the first and second electrode layers includes a base member having a major surface on which a plurality of concave portions are formed so that the base member has a honeycomb structure or a pinholder-shape structure and an electrode material filled in at least the concave portions so as to extend from the honey comb structure or the pinholder-shape structure toward the electrolyte layer and form an electrode material layer, the major surface facing to the electrolyte layer, wherein an average depth of the concave portions is in the range of 50 to 400 μm, wherein an occupation percentage of the concave portions with respect to the major surface of the base member in a plan view is 25 to 85%, and wherein an average thickness of the electrode material layer is in the range of 5 to 120 μm.
