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.
