ELECTRICAL COMPONENT, NONAQUEOUS-ELECTROLYTE CELL, AND LEAD WIRE AND SEALABLE CONTAINER BOTH FOR USE THEREIN

Provided are an electrical part, a nonaqueous electrolyte cell, and a lead wire and a sealable container which are used therein. The electrical part includes a sealable container having a metal layer, and a lead conductor extending from the inside to the outside of the sealable container, the sealable container and the lead conductor being fusion-bonded at a sealing portion, in which the sealing portion at least partially has a layer composed of a polyallylamine at a part between the metal layer and the lead conductor and in contact with the lead conductor, and therefore, adhesion and sealing properties can be enhanced in the initial state and in a state of being in contact with an electrolytic solution.
