<P>PROBLEM TO BE SOLVED: To provide an electric component, a nonaqueous electrolyte battery, and a lead wire and an encapsulation container used therefor, which make it possible to heighten the adhesiveness and sealability in an initial state and in a contacted-with-electrolyte state. <P>SOLUTION: An electric component includes an encapsulation container having a metal layer and a lead wire extending from the inside to the outside of the encapsulation container, with the encapsulation container and the lead wire heat-sealed together in a sealing section, characterized in that at least part of the sealing section has a heat-seal layer having a sulfonyl group or a sulfo group in a portion, situated between the metal layer and the lead wire, which abuts on the lead wire. The heat-seal layer should preferably be a copolymer derived from sulfonation-treated acid modified polyolefin or an olefin based monomer having a sulfonyl group or a sulfo group as a copolymerization monomer. <P>COPYRIGHT: (C)2012,JPO&INPIT |
