摘要： Provided is a sealed battery that can offer excellent battery performances by having its electrode terminal and a current collector securely welded to each other, and its manufacturing method. The sealed battery is formed by hermetically sealing a casing storing an electrode assembly and the current collector, wherein: the electrode assembly formed by layering positive and negative electrode plates with a separator sandwiched therebetween is electrically connected to the current collector; and a shaft portion of the electrode terminal penetrates through the current collector. A part of the electrode terminal projecting out from a pass-through of the current collector is a (conical) frustum-shaped portion whose bottom base is in contact with the current collector. The frustum-shaped portion is pressed against the current collector, and the frustum-shaped portion and the current collector are welded together in at least one area on a perimeter of the bottom base of the frustum-shaped portion.
