The present invention relates to an all-solid-state rechargeable battery in which the protrusions and recesses of the surface of the all-solid-state rechargeable battery are reduced, and a current-collecting portion is difficult to crack or cut. The all-solid-state rechargeable battery includes a first electrode layer that is either a positive electrode layer or a negative electrode layer; solid electrolyte layers stacked on both surfaces of the first electrode layer, respectively; a second electrode layer that is the other of the positive electrode layer or the negative electrode layer stacked on the outer surfaces of the solid electrolyte layers, respectively; an insulating layer disposed on a side end surface of the first electrode layer; and a thin current-collecting portion protruding from the first electrode layer through the insulating layer to the outside, wherein a side end surface of the insulating layer on the side from which the current-collecting portion protrudes has a roughened portion having a surface roughness that differs from that of another side end surface of the insulating layer.
