Abstract

A cell module includes: a battery cell group configured with a plurality of cylindrical battery cells; a positive current collector; and a negative current collector. The negative current collector has: a substrate disposed on a sealing body side of the cylindrical battery cells such that the negative current collector covers the battery cell group; and a current collecting pin protruding toward the battery cell group from the substrate. The current collecting pin is inserted into a gap between the cylindrical battery cells along an axial direction of such battery cells, and presses the side surfaces of outer cans of at least two cylindrical battery cells neighboring each other.
