摘要： The present invention relates to an apparatus for ultrasonic welding for improving the welding strength between an electrode tap and an electrode lead which comprise a secondary battery, and to a secondary battery which is welded by the apparatus for ultrasonic welding so as to improve the strength of a welded area. The secondary battery according to the present invention comprises: an electrode assembly on which a positive electrode plate having a positive tap, a negative electrode plate having a negative tap, and a separator are alternately stacked; an exterior pouch material for receiving the electrode assembly; a positive electrode lead welded and electrically connected to the positive electrode tap; and a negative electrode lead welded and electrically connected to the negative tap. A welded point of a welded surface between the negative electrode lead and the negative electrode tap has a density greater than that of a welded point of a welded surface between the positive electrode lead and the positive electrode tap.
