A battery pack is provided and includes a battery unit. The battery unit includes multiple batteries and one or more heat-absorbing members. For example, the one or more heat-absorbing members each include a heat-absorbing agent and a housing body housing the heat-absorbing agent. The one or more heat-absorbing members each extend in an axial direction of the batteries, and are each disposed to be adjacent to at least two of the batteries. The battery unit further includes a battery holder, a first tab, and a second tab. The battery holder holds the batteries. The first tab is coupled to a terminal on one end side of each of the batteries. The second tab is coupled to a terminal on another end side of each of the batteries. The first tab is provided to cover, when the battery unit is viewed in the axial direction of the batteries, one end of each of the one or more heat-absorbing members. The second tab is provided to cover, when the battery unit is viewed in the axial direction of the batteries, another end of each of the one or more heat-absorbing members.
