The present invention relates to an all-solid-state battery, which comprises a cathode including a cathode active material layer containing a cathode active material, an anode including an anode catalyst layer containing an anode catalyst and Nb2O5, and an electrolyte, wherein the anode catalyst layer contains Nb2O5 at a content of 1 to 30 weight% on the basis of a total of 100 weight% of the anode catalyst layer and the ratio (N/P) of the capacity of the anode catalyst layer to that of the cathode is between 0.1 (inclusive) and 0.5 (exclusive). La présente invention concerne une batterie tout solide, qui comprend une cathode comprenant une couche de matériau actif de cathode contenant un matériau actif de cathode, une anode comprenant une couche de catalyseur d'anode contenant un catalyseur d'anode et Nb2O5, et un électrolyte, la couche de catalyseur d'anode contenant Nb2O5 à une teneur de 1 à 30 % en poids sur la base d'un total de 100 % en poids de la couche de catalyseur d'anode et le rapport (N/P) de la capacité de la couche de catalyseur d'anode à celle de la cathode étant compris entre 0,1 (inclus) et 0,5 (exclus). 전고체 전지에 관한 것으로서, 이 전고체 전지는 양극 활물질을 포함하는 양극 활물질층을 포함하는 양극, 음극 촉매 및 Nb2O5를 포함하는 음극 촉매층을 포함하는 음극, 및 전해질을 포함하고, 상기 Nb2O5의 함량은 상기 음극 촉매층 전체 100 중량%에 대하여 1 중량% 내지 30 중량%이고, 상기 양극의 용량에 대한 상기 음극 촉매층의 용량 비율(N/P)은 0.1 이상, 0.5 미만인 것이다.
