A film-sealed nonaqueous electrolyte battery comprises: a battery element including
a non-aqueous electrolyte; a film case having at least a sealant polymer resin
film for sealing the battery element; at least a lead terminal extending from the
battery element and projecting from the film case, and the lead terminal with a
surface having a contact area in contact directly with the sealant polymer resin
film, and at least the contact area of the surface of the lead terminal is coated
with an anti-corrosion coating film, wherein the anti-corrosion coating film includes:
(A) a polymer of structural units of a phenolic compound, and at least a part of
the structural units includes a substituent which comprises an amino group or a
substituted amino group; (B) a phosphate compound; and (C) a titanium fluorine compound.
