PROBLEM TO BE SOLVED: To provide an all-solid battery capable of absorbing hydrogen sulfide gas generated by a power generation element and making it harmless without lowering volume energy density. SOLUTION: The all-solid battery includes a case having a first concave part for housing a power generation element, a second concave part formed on an outer periphery of the first concave part and for housing a hydrogen sulfide harmless part, and an adhesion part having an outer peripheral adhesion part arranged at least on an outer periphery of the second concave part, an outer package material consisting of a lid body for sealing the first concave part and the second concave part by adhering with the outer peripheral adhesion part, a power generation element having a cathode layer, an anode layer and a solid electrolyte layer arranged between the cathode layer and the anode layer, and housed in the first concave part, and a hydrogen sulfide harmless part having a hydrogen sulfide harmless agent and housed in the second concave part. The all-solid battery contains sulfide system solid electrolyte containing sulfur on at least either the cathode layer, the anode layer or the solid electrolyte layer. COPYRIGHT: (C)2011,JPO&INPIT
