ELECTRICAL COMPONENT, NONAQUEOUS ELECTROLYTE BATTERY, AND LEAD WIRE AND SEALING CONTAINER EACH USED IN ELECTRICAL COMPONENT OR NONAQUEOUS ELECTROLYTE BATTERY

摘要

Provided are: an electrical component and a nonaqueous electrolyte battery, each of which has improved adhesion and sealing performance in the initial state and in a state being in contact with the electrolyte solution; and a lead wire and a sealing container, each of which is used in the electrical component or in the nonaqueous electrolyte battery. This electrical component is provided with a sealing container which comprises a metal layer and a lead conductor which extends from the inside of the sealing container to the outside of the sealing container, and is obtained by thermally fusion-bonding the sealing container and the lead conductor at a sealing portion. At least a part of the sealing portion, namely a portion which is between the metal layer and the lead conductor and is in contact with the lead conductor has a thermal fusion layer that contains fused aluminum phosphate.
