BATTERY ACCOMMODATION TRAY

The purpose of the present disclosure is to provide a battery accommodation tray in which the amount of material used is readily reduced and of which the strength is readily improved. The battery accommodation tray comprises a plurality of accommodation parts that respectively accommodate batteries and that are positioned at intervals from each other. The accommodation parts have insertion openings demarcated by insertion-side circular parts that have a circular shape when viewed from the insertion side of the batteries in the height direction (Z direction). The battery accommodation tray has insertion-side connection parts by which the outer peripheral surfaces of the insertion-side circular parts are connected to the outer peripheral surfaces of adjacent insertion-side circular parts. The plurality of insertion-side circular parts are connected by the plurality of insertion-side connection parts to form an integrated whole.
