Abstract: A thermoelectric conversion element that includes a laminated body having a plurality of first thermoelectric conversion portions, a plurality of second thermoelectric conversion portions, and an insulator layer. The first thermoelectric conversion portions and the second thermoelectric conversion portions are alternately arranged in a Y-axis direction and bonded to each other in first regions, and the insulator layer is interposed between the first thermoelectric conversion portions and the second thermoelectric conversion portions in second regions. The insulator layer surrounds a periphery of each of the second thermoelectric conversion portions. A ratio (W2/W1) of a thickness (W2) of the first thermoelectric conversion portion to a thickness (W1) of the second thermoelectric conversion portion in the Y-axis direction is greater than 4 and 11 or less.

Abstract: A thermoelectric conversion element includes a laminated body including a plurality of first thermoelectric conversion parts, a plurality of second thermoelectric conversion parts, and an insulator layer. The first thermoelectric conversion parts and the second thermoelectric conversion parts are alternately arranged in the Y axis direction and the first thermoelectric conversion part and the second thermoelectric conversion part are joined in a region of the surface between the first thermoelectric conversion part and the second thermoelectric conversion part in the Y axis direction, and in the other region of the surface in the Y axis direction, the insulator layer is interposed between the first thermoelectric conversion part and the second thermoelectric conversion part. The laminated body has a first principal surface and a second principal surface at both ends in the Y axis direction, and both end surfaces in a direction perpendicular to the Y axis direction. The insulator layer covers the end surface of the second thermoelectric conversion part.

Abstract: A solid-state battery including a solid-state battery laminate that includes at least one battery constituent unit including a positive electrode layer, a negative electrode layer, and a solid electrolyte layer interposed between the positive electrode layer and the negative electrode layer along a lamination direction, and defining: an overlapping part in which the positive electrode layer and the negative electrode layer overlap each other in the lamination direction, and a non-overlapping part in which the positive electrode layer and the negative electrode layer do not overlap each other in the lamination direction. At least one main surface having a normal in the lamination direction has a recess overlapping the overlapping part and defines a step between the overlapping part and the non-overlapping part or in the non-overlapping part.
