description A battery module of the present invention comprises an annular connecting member 10 having an aperture 14 at a position corresponding to a cap 8 provided on a sealing plate 7 and between the sealing member 7 of one cell B and a bottom of a can 6 of the other cell A. The annular connecting member 10 comprises an annular base portion 11 having its outer diameter smaller than an inner diameter of the opening portion of the can 6, a convex portion 12 with bottom protruding upward or downward alternately from the annular base portion 11, and a projection 13 projecting from the bottom of the convex portion 12. Thereby, the connecting portion between the cell A and the cell B has a collecting path of a length between both projections 13, namely, a length between the sealing plate 7 of the cell B and the bottom of the can 6 of the cell A, whereby the voltage drop across the connecting portion decreases, resulting in a battery module having high operation voltage.
