PURPOSE: An assembly body of a secondary battery is provided to reduce resistance because a contact point is increased and contact resistance is reduced, when discharging a battery with a high capacity, by electrically connecting an electrode with a current collector through using a mesh-shaped metal grid, to easily function a heat diffusing operation of the battery, to increase yield when fabricating the battery by preventing electrode damage or an active material being falling off, because an electrode contactor does not have a projected form. CONSTITUTION: An assembly body of a secondary battery comprises a case(12), an electrode assembly body(14), an anode current collector(32), an anode portion plate(40), and a cathode current collector(72). The electrode assembly body is located in the case, and an anode(20), a separator(18), a cathode(16) are wound thereon. The anode current collector is located in an upper part of the electrode assembly body, and has an anode grid(31) and a conductive anode current collecting plate(32) supporting the anode grid with a mesh-shape, which is connected with the anode. The anode portion plate is located in an upper part of the case, and is electrically connected to the anode current collector. The cathode current collector is located in a lower side of the electrode assembly body, and has a cathode grid(71) with a mesh-shape and a conductive cathode current collecting plate(72) supporting the cathode grid. The anode portion plate is located in a lower part of the case, and is electrically connected to the cathode current collector.
