Secondary Battery Having Improved Terminal Structure

Abstract: The disclosed invention relates to a secondary battery comprising: a positive electrode terminal and a negative electrode terminal disposed apart from each other on a top surface of a battery case in a hexahedron shape; and a terminal structure comprising a terminal body which surrounds the positive electrode terminal or the negative electrode terminal such that the positive electrode terminal or the negative electrode terminal is not exposed, and is coupled to the top surface of the battery case and one or more surfaces connected to the top surface, and an extension terminal which is electrically connected to the positive electrode terminal or the negative electrode terminal and is exposed to any one surface of the terminal body excluding a top surface thereof, the extension terminal being electrically connected to the positive electrode terminal or the negative electrode terminal by means of an extension wire, wherein the extension wire has a bonding portion with respect to the positive electrode terminal or the negative electrode terminal and the bonding portion is insulated from the outside.
