A spool for a dual-bearing reel includes a bobbin trunk having a tubular shape, a pair of flanges and a plurality of first through holes. Each flange is provided on opposite ends of the bobbin trunk, each flange having a circular shape and a larger diameter than the bobbin trunk. The first through holes are provided in at least one flange of the pair of flanges and are circumferentially disposed at intervals about the at least one flange. The first through holes open in a radial position located at a distance away from an outer peripheral surface of the bobbin trunk, the distance being less than or equal to a second distance from the outer peripheral surface oft he bobbin trunk, the second distance being 60% of a distance from the outer peripheral surface of the bobbin trunk to an outer peripheral surface of the at least one flange.
