<P>PROBLEM TO BE SOLVED: To reduce the electrical resistance of a secondary battery and a bus bar while enhancing the workability of bus bar attachment work. <P>SOLUTION: A bus bar 50 connecting the terminals 61, 71 of the external positive electrode and the negative electrode of a secondary battery 1 has a substantially flat and planar base 51, and a plurality of heat radiation fins 52 standing substantially perpendicularly to the base 51. An attachment part 51a having a pair of through holes 53 is formed in the base 51, and the heat radiation fin 52 is not formed in the attachment part 51a. The terminals 61, 71 of the external positive electrode and the negative electrode having a bolt structure penetrate the through holes 53, and the bus bar 50 is fastened to a battery cover 3 by means of nuts 57. <P>COPYRIGHT: (C)2013,JPO&INPIT |
