1. A method for manufacturing a pipe type busbar, the method comprising:
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;
bonding one surface of the first tubular member and one surface of the second tubular member to one another;
machining the first tubular member to form a stepped part so that a diameter of another surface of the first tubular member is smaller than a diameter of one surface thereof;
machining an outer surface of an area having a larger diameter than the stepped part of the first tubular member after bonding; and
removing the third material such that the first material of the first tubular member is exposed by the machining of the outer surface of the area having the larger diameter than the stepped part of the first tubular member.
