NOVELTY - An electric energy storage device comprises a terminal plate (300) including a cathode lead connecting plate (320) having a cathode terminal (340) and a cathode lead connecting portion closely contacted with cathode leads (225), and an anode lead connecting plate having an anode terminal (360) and an anode lead connecting portion closely contacted with anode leads (235).    USE - Thin film type capacitor, electrolytic capacitor, ultra-capacitor and secondary battery for electrical or electronic apparatus.    ADVANTAGE - The electric energy storage device has reduced volume, enhanced convenience, and improved productivity. Productivity of a manufacturing process for the electric energy storage device may be improved.    DETAILED DESCRIPTION - An electric energy storage device comprises a cylindrical rolling up electrode body including a cathode, a separator, an anode, a winding spool, cathode leads formed by cathode collectors, and anode leads formed by anode collectors, where cathode, separator, and anode are sequentially wound around the winding spool, and the cathode leads and the anode leads are separately extended from one side of the rolling up electrode body; a terminal plate including a cathode lead connecting plate having a cathode terminal and a cathode lead connecting portion closely contacted with the cathode leads, an anode lead connecting plate having an anode terminal and an anode lead connecting portion closely contacted with the anode leads, and an insulation combing component (370) for integrally combining the cathode lead connecting plate with the anode lead connecting plate, where cathode lead connecting plate is electrically insulated from the anode lead connecting plate; and a container for receiving the rolling up electrode body. An INDEPENDENT CLAIM is also included for a method of manufacturing an electric energy storage device, comprising forming a rolling up electrode body by winding a cathode, a separator, and an anode, and by partially cutting the cathode and the anode so that cathode leads and anode leads are separately extended from one side of the rolling up electrode body; forming a terminal plate including a cathode lead connecting plate having a cathode terminal and a cathode lead connecting portion, and an anode lead connecting plate having an anode terminal and an anode lead connecting portion, where cathode lead connecting plate is electrically insulated from the anode lead connecting plate; inserting the rolling up electrode body into a container; sealing the terminal plate and the container while the cathode and the anode lead connecting portions are closely contacted with the cathode and the anode leads, respectively; combining the cathode and the anode lead connecting portions with the cathode and the anode leads, respectively.
