A stack-type isotope battery comprises: a plurality of stacked isotope electrode sheets, each of the isotope electrode sheets including: a substrate having a first layer and a second layer and a cavity extending in the substrate thickness direction; and a radiation source accommodated in the cavity, wherein the first layer is interposed between the radiation source and the second layer, wherein the plurality of isotope electrode sheets are stacked on top of one another in a direction parallel to the substrate thickness direction; and a first external electrode of first polarity and a second external electrode of second polarity respectively connected to the plurality of stacked isotope electrode sheets to provide an electrical connection to an external load. The substrate has a chemical formula of AMO3 (where A is one or more selected from the group consisting of La, Ba, Sr, and K, and M is one or more selected from the group consisting of Al, In, Ga, Ti, Sn, Hf, Ta, and Zr). The first layer is doped with dopants of a first conductive type and a second layer is either doped with dopants of a second conductive type different from the first conductive type or undoped.
