<p>Corners 3a', 3b' of anode collector 3a and cathode collector 3b are covered with collector protection member 10. Collector protection member 10a is a member in the form of a bag of a resin-made film, and is formed at front surface 10c thereof with insertion hole 10d for allowing anode tab 4a and anode collector 3a or cathode tab 4b and cathode collector 3b to be inserted thereinto. Collector protection member 10 is vacuumed when battery element 2 is sealed with laminate films 5, 6, thereby ensuring tight contact of collector protection member 10 with anode collector 3a and cathode collector 3b.</p> |
