Problems solved by technology

However, with this invention, since short circuits are likely to occur at temperatures exceeding the melting point of the low-fluidity resin, it is rather difficult to achieve good adhesion with heat sealing performed under such conditions to avoid short circuits.

Abstract

An electrical part comprises a sealed vessel comprising a metal layer and a lead conductor extending from the inside to the outside of the sealed vessel, the lead conductor and the sealed vessel having been fused to each other at a sealing part through a fusion bonding layer. The electrical part has, between the metal layer and the lead conductor in the sealing part, a layer which is difficult to soften and has through-holes extending in the thickness direction. Also provided are: a nonaqueous-electrolyte cell comprising a sealed vessel and, enclosed therein, a nonaqueous electrolyte and electrodes; and a lead conductor coated with an insulating coating layer and a sealed vessel which are for use in this electrical part, etc.

Description

technical field [0001] The present invention relates to electrical components used in electronic equipment and the like, and particularly to nonaqueous electrolyte batteries used as power sources for small electronic equipment and the like. The invention also relates to a wire conductor with an insulating covering and a sealed container, which are constituent elements of an electrical component. Background technique [0002] In accordance with the trend of miniaturization of electronic equipment, miniaturization and lightening of electrical components used in electronic equipment has been required. Therefore, in the case of power sources, for example, there is a tendency to adopt a nonaqueous electrolyte battery manufactured using a pouch for sealing a container and encapsulating a nonaqueous electrolyte, a cathode, and an anode therein. [0003] Such a sealed container is required to have properties capable of preventing not only electrolyte and gas from permeating but als...
