Abstract: A sealed battery includes a battery case including a mounting hole, an internal terminal disposed in the battery case and including a shaft portion inserted through the mounting hole, an external terminal disposed on an outside of the battery case and including an insertion hole through which the shaft portion of the internal terminal is inserted, and a gasket and an insulator interposed between the battery case and the internal terminal and between the battery case and the external terminal to insulate the internal terminal and the external terminal from the battery case. The shaft portion of the internal terminal is fastened to the insertion hole of the external terminal. The external terminal includes a raised portion provided around a portion of the external terminal onto which the shaft portion of the internal terminal is fastened.

Abstract: A calibration area has a rectangular area and a peripheral area. The rectangular area includes a center area provided in the center portion and a first corner area, a second corner area, a third corner area, and a fourth corner area that are set at four corners sequentially in the circumferential direction. The center area has a line symmetry with respect to each of the two orthogonal axes passing through the center of the rectangular area. The heights of the areas are different.

Abstract: A sealed-type battery includes an exterior body, a collector terminal, a hollow rivet defining a hollow section, and a reverse plate arranged between the collector terminal and the hollow rivet. The collector terminal includes: a projected section projected; a peripheral edge section provided; and a notch section provided in the peripheral edge section in a manner to surround the projected section and formed in a manner to reduce thickness of the collector terminal. In a projected direction of the projected section, the projected section is thicker than the peripheral edge section. A fitting section, to which the projected section is fitted, is provided in the reverse plate. The sealed-type battery includes a welded section that has a top surface opposing the hollow rivet and that joins the collector terminal and the reverse plate at a position between the projected section and the fitting section.

Abstract: A region of a hole-inner circumferential surface composing a portion defining a terminal through-hole, the region being located on the battery case cover side, include a tapered surface gradually enlarged in diameter as extending toward the battery case cover side and opening toward the battery case cover side; when riveting is carried out, a region of a shaft portion, the region being located inward of the tapered surface, is enlarged in diameter so as to form an annular projecting portion in contact with the tapered surface; and a hole circumferential portion located around the portion defining the terminal through-hole is held between the external enlarged-diameter portion and the annular projecting portion so as to fix a first terminal member to a second terminal member.
