Abstract
A battery block includes a holding unit that holds a plurality of cells. The holding unit is made of a material having a heat conductivity. The holding unit includes openings that are open over the entire length of the side surfaces of the cells in the longitudinal direction. Each opening is formed so that, on the side surface of each cell, the area of a first region exposed to the outside through the opening is smaller than that of a second region other than the first region.
