<P>PROBLEM TO BE SOLVED: To provide a sealed battery which prepares an electrode terminal having a function for releasing pressure to the outside at the time of rise of internal pressure of the battery and improves manufacturing operability for mounting the electrode terminal on a sealing plate and improves voltage-resistant performance. Ž<P>SOLUTION: The sealed battery comprises the sealing plate 8 which seals an opening at one end of a battery case 2 and made from a conductor as one electrode, the other electrode terminal 12 located in a through-hole 10 arranged on the sealing plate and made from a hollow cylindrical conductor extended over the inside and outside of the battery case by forming flanges 17, 18 spreading outward to both ends, and an insulating member 15 made of a synthetic resin which is integrally molded with the sealing plate and the electrode terminal by covering an outer peripheral surface of a flange section and a hollow cylindrical section 14 of the electrode terminal and by wrapping a peripheral edge section of the through-hole of the sealing plate. A hollow section of the hollow cylindrical electrode terminal is blocked by a thin film section 25. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
