1. A welding horn for a secondary battery, configured for use in ultrasonic welding, the welding horn comprising:
a body portion having coupling portions respectively provided at one and the other ends thereof; and two tip portions provided at a central portion of the body portion and having protruding portions provided on a surface thereof, wherein a nitride is coated on at least one surface of the welding horn, each of the protruding portions protrudes in the shape of a triangular pyramid of which the base side mounted on the surface of the tip portion is quadrangular, wherein the body portion has two flat surfaces extended in a first direction, and the first direction is a direction extended from the one end to the other end of the body portion; wherein the two flat surfaces are on opposite sides of the body portion; wherein the tip portions protrude from the flat surfaces, and extend in a second direction perpendicular to the first direction so as to traverse the flat surface; wherein the tip portions protrude from the flat surface and have rod shapes which each contact one of the flat surfaces from an upper end portion to a lower end portion of the flat surface; and wherein the tip portions protrude from the flat surfaces so as to have a height lower than the one end and the other end of the body portion. |
