ELECTRIC STORAGE APPARATUS AND METHOD FOR PRODUCING THE ELECTRIC STORAGE APPARATUS

摘要

Provided is an electric storage apparatus including: an electric storage device including an external terminal that has a first connection surface; a bus bar having a second connection surface that overlaps the first connection surface; a first weld portion that is formed extending over the external terminal and the bus bar in a region where the first connection surface and the second connection surface are opposed to each other; and a second weld portion that is formed extending over the external terminal and the bus bar in a region where the first connection surface and the second connection surface are opposed to each other, the second weld portion overlapping the first weld portion, wherein the second weld portion is formed such that its weld center is displaced from a weld center of the first weld portion. Also provided is a method for producing the electric storage apparatus.
