PROBLEM TO BE SOLVED: To lower manufacturing cost by a simple structure, and to arrange protective elements in an outer package can in an ideal state. SOLUTION: A packed battery has an opening of the outer package can housing an electrode body 18 occluded by a sealing plate 3 having a convex electrode 4. The convex electrode 4 is connected with one of the electrodes of the electrode body 18 through protective elements 10, and a plastic-made insulation spacer 40 is arranged between the sealing plate 3 and the electrode body 18. The protective elements 10 have a main body chip 12 for connecting a first connecting metal terminal 11A and a second connecting metal terminal 11B. Furthermore, the packed battery has the main body chip 12 insert-molded into the insulation spacer 40 molded in plastic, and the protective elements 10 are arranged in the outer package can 2. The protective elements arranged in the outer package can safely protect the battery by quickly operating by heat generated by the battery. COPYRIGHT: (C)2008,JPO&INPIT
