A battery pack according to one aspect of the present technology includes a plurality of batteries, a holder that is capable of supporting the plurality of batteries, and an elastic body that is provided between the batteries and the holder. Each battery has an end surface on which a positive electrode terminal having a convex shape is formed. The holder has a side plate portion provided with a first opening at a place facing the positive electrode terminal. The elastic body includes a sheet portion and a projection. The sheet portion is arranged in a region between the end surface of the battery and the side plate portion of the holder. The sheet portion is provided with a second opening having an opening diameter smaller than that of the first opening at a place facing the positive electrode terminal. The projection is configured to project toward both the side plate portion side and the positive electrode terminal side of the sheet portion, and to be in contact with the side plate portion and the positive electrode terminal.
