ABSTRACT:
An electrochemical cell has an outer case formed of one of ceramics and glass. An electrochemical cell element is hermetically sealed in the outer case. The electrochemical cell element contains a positive pole, a negative pole, and a non-aqueous electrolyte containing an organic solvent. A metal layer is formed on an edge of the outer case. A sealing plate is resistance welded to the metal layer. The sealing plate is made of an alloy containing, in weight percentage, Co by 1 to 50%, Ni by 1 to 70%, Fe by 20% or higher, Cr by 10% or lower, Mn by 2.0% or lower, Si by 1.0% or lower and C by 1.0% or lower.
