A couple structure of an electrode tap and an electrode terminal is provided to suppress a short circuit between electrodes and the impairment of a battery cell when an electrode terminal is deformed by external shock. A couple structure of an electrode tap and an electrode terminal for a secondary battery includes: a battery cell(100) having a laminate of a positive electrode plate, a separator, and a negative electrode plate; electrode taps(110,120) extended from one side of each of the positive electrode plate and negative electrode plate; and electrode terminals(210,220) which are electrically connected with the electrode taps. The electrode terminal is a square strap of a metal material having predetermined thickness and length. The square strap and electrode tap are electrically combined by welding. Two corners of the square strap combined with the electrode tap are round-shaped. |
