TERMINAL COMPONENT AND METHOD OF MANUFACTURING TERMINAL COMPONENT

摘要

A terminal component includes an external terminal that is provided above a cover covering an electrode body; and an internal terminal that is provided below the cover and extends through a through-hole of the external terminal. A part of the internal terminal protrudes above the external terminal. A dimension of the part of the internal terminal in a radial direction of the through-hole is larger than a diameter of the through-hole. The external terminal has a joint surface that is a first part of an upper surface of the external terminal and that is joined to the internal terminal, and a non-joint surface that is a second part of the upper surface of the external terminal and that is located outside the joint surface. The joint surface is located higher than at least part of the non-joint surface.
