A partial battery pack structure includes a battery group, heat transfer plates, and a radiator, and is formed by stacking layers. Each layer arranges cylindrical batteries in parallel in a plane. The batteries in adjacent layers have alignment pitches shifted by a half pitch from each other. Each heat transfer plate contacts side surfaces of the batteries on both surfaces of the heat transfer plates, is formed by a heat transfer corrugated plate member, and extends through a gap between the batteries along an alignment direction of the cylindrical batteries in the layers in the plane intersecting center axis lines of the cylindrical batteries, a first intersection direction intersecting the alignment direction or a second intersection direction intersecting the alignment direction and the first intersection direction. The radiator is on a side of the battery group and connects with each heat transfer plate. Each battery contacts two or more heat transfer plates.
