Disclosed is a nonaqueous electrolyte secondary battery comprises a sealing
unit including a conductive support plate, wherein the conductive support plate
contains at least one kind of a conductive material selected from the group consisting
of a metal, an alloy and a composite metallic material, each of the metal, the
alloy and the composite metallic material has a modulus of elasticity (Young's
modulus) at 25 C. that falls within a range from 11011 Pa
to 3.271011 Pa, and the conductive support plate has an area resistance
value RS at 20 C. falling within a range from 0.032 (cm2)
to 1.24 (cm2).
