Claim 0:
1. A nonaqueous electrolyte battery, comprising:
an enclosing container; and
a plurality of lead wires for a nonaqueous electrolyte battery arranged so as to extend from the inside of the enclosing container to the outside thereof,
wherein the enclosing container comprises a sheet body having an innermost resin layer, a metal layer and an outermost resin layer laminated in this order;
the lead wires for the nonaqueous electrolyte battery, comprises:
a conductor; and
an insulating film having a plurality of layers and covering at least a part of an outer peripheral surface of the conductor,

wherein the insulating film has a conductor-covering layer laminated on a surface of the conductor, a first insulating layer laminated on an outermost surface of laminated on an outermost surface of the insulating film, and a second insulating layer laminated on an inner surface of the first insulating layer,
the conductor-covering layer comprises an acid-modified polyolefin,
a ratio (E1/E2) of an elastic modulus E1 of the first insulating layer at any one temperature in the range of 80° C. or more and 125° C. or less to an elastic modulus E2 of the second insulating layer at the same temperature as in the first insulating layer, is 0.25 or more and 0.67 or less,
the innermost resin layer and the first insulating layer are thermally fused, and
a ratio (E4/E1) of an elastic modulus E4 of the innermost resin layer at any one temperature in the range of 80° C. or more and 125° C. or less to the elastic modulus E1 of the first insulating layer at the same temperature as in the innermost resin layer, is 0.60 or more and 1.76 or less.
