Original Abstract Submitted

an ultrasonic welding apparatus, configured to weld a plurality of electrode tabs of an electrode assembly to each other, includes an anvil disposed at one side of the plurality of electrode tabs; a horn disposed to face the anvil with the plurality of electrode tabs therebetween; and a protrusion part provided on at least one of the anvil and the horn to face the plurality of electrode tabs. the protrusion part may include: an inner protrusion part in which a plurality of first protrusions are arranged along a first direction parallel to a width direction of the electrode tabs; and a pair of outer protrusion parts which are disposed at both sides of the inner protrusion part in a second direction orthogonal to the first direction and in which a plurality of second protrusions are arranged an interval wider than that between the plurality of first protrusions.
