Zusammenfassung:	PURPOSE:To prevent leakage at a connecting part, and to provide a sealed secondary battery, which can extend life and improve reliability. CONSTITUTION:An alpha-alumina ring 2 is connected to the opening part of a solid electrolytic tube 1 by glass soldering, and a negative electrode lid 3 is connected to one surface of the alpha-alumina ring 2, while a positive electrode lid 4 is connected to the other surface of the ring 2. The connection is carried out by interposing an aluminium layer 12 containing silicon and at least one metal chosen from among manganese, copper, magnesium, and calcium. Since an aluminium layer of the connected part between the negative electrode lid 3 and the alpha-alumina ring 2 and aluminum of the connected part between the positive electrode lid 4 and the alpha-alumina ring 2 can be activated, airtightness can be improved.
