Provided are a method of manufacturing an all-solid battery and an all-solid battery manufactured by the method. The all-solid batter may have edge portions that can be more effectively insulated. In particular, the all-solid battery may include a cathode layer, an anode layer, and an electrolyte layer, a first insulator disposed at an edge of the cathode layer and a second insulator disposed between the cathode layer and the first insulator, thereby forming a membrane of the second insulator for preventing contact between the cathode layer and the anode layer in pressing.
