Abstract
Provided are a battery block and a secondary battery module capable of holding a plurality of battery cells stably and so reducing a load applied to a welding part of a conductive member that is connected to an electrode by welding or the like. The battery block includes a lower holding frame and a middle holding frame, one of which includes two protrusions that are in contact with an outer peripheral face of each battery cell and the other includes a pressing part that presses the outer peripheral face of the battery cell inwardly in the radial direction. Then, one of an upper holding frame and the middle holding frame includes two protrusions that are in contact with an outer peripheral face of each battery cell and the other includes a pressing part that presses the outer peripheral face of the battery cell inwardly in the radial direction.
