Abstract
An electrochemical cell which includes a sealed metallic container at least partially composed of an anode metal member and a cathode metal member, said container containing a power generating material. At each edge portion of the metal members is covered by a seal material including a coating layer of thermoplastic resin containing a functional group with hydrogen bonding capability. Sealing of the metallic container is achieved by heat-pressure bonding the seal members formed on the respective metal members with each other or these seal members with similar seal members formed on another metal member forming the metallic container.
