Abstract: A method for manufacturing a pipe type busbar includes: preparing a first tubular member made of a first material having a hollow formed therein; preparing a second tubular member having a hollow formed therein and made of a second material different from the first material; plating the first tubular member with a third material; and bonding one surface of the first tubular member and one surface of the second tubular member.

Abstract: A method for manufacturing a pipe type busbar includes: preparing a first tubular member made of a first material having a hollow formed therein; preparing a second tubular member having a hollow formed therein and made of a second material different from the first material; plating the first tubular member with a third material; and bonding one surface of the first tubular member and one surface of the second tubular member. The pipe type busbar manufactured thereby has the features capable of reducing a weight and a cost by a heterogeneous material, a pipe shape, and exposing a part of a copper material.

Abstract: A bus bar and a method of manufacturing the same may include a first metal portion made of a first metal material; and a second metal portion made of a second metal material different than the first metal portion. The first metal portion and the second metal portion are coupled by a rotation friction welding (RFW).
