<P>PROBLEM TO BE SOLVED: To provide a small sized lithium battery with a long service life, can be loaded to a circuit substrate without using needless parts, etc., and with little deterioration in discharge capacity even with repeated charging and discharging. <P>SOLUTION: The lithium battery 20 is formed by having an electricity generating element 1 consisting of a laminated body sequentially laminated with a positive electrode 7, electrolyte 12 and a negative electrode 10 on a base plate 3 provided with a positive electrode extracting part 5, and a negative electrode extracting part 6 loaded; electrically connecting the positive electrode 7 with the positive electrode extracting part 5 at a positive end electrode 13 and the negative electrode 10, and the negative electrode extracting part 6 at a negative end electrode 16; and then having a lid body 2 joined to the base plate 3. The positive and the negative end electrodes 13 and 16 are each formed by two layers of conductive resin layers 14, 15, 17 and 18; the conductive material contained in the inner conductive resin layers 14 and 17 are formed by material not easily reacting to the electrodes 7 and 10; and the conductive material contained in the outer conductive resin layers 15 and 18 are formed by conductive material easily reacting to the electrodes 7 and 10. <P>COPYRIGHT: (C)2003,JPO |
