BUS BAR

A bus bar that can be simply and easily identified as having generated abnormal heat. [0002] An insulator 3 has an interior S formed hollow and is made of heat-shrinkable resin. A bus bar main body 2 is inserted into the hollow, and an identification member 4 that can identify abnormal heat generation when the insulator 3 is heat-shrunk due to the abnormal heat generation is provided in the hollow. Also, in fixing a part of the insulator 3 to the bus bar main body 2, the insulator 3 is fixed to the bus bar main body 2 by heat-shrinking both end sides of the insulator 3 so as not to come in contact with a left bolt hole 2a1 and a right bolt hole 2b1.
