A spool of a dual-bearing reel includes a bobbin trunk, first and second flange portions and cylindrical portions. The first flange portion extends outwardly from the first end of the bobbin trunk and the second flange portion extends outwardly from the second end of the bobbin trunk. The first and second flanges do not have through-holes penetrating therethrough in an axial direction. The cylindrical portions extend outwardly from distal end portions of the flange portions. The first and second flange portions have a first tapered portion and a second tapered portion, respectively, each of the first and tapered portions becoming thinner in a radially outward direction. An average width between the first and tapered portions is less than or equal to 60% of an outer diameter of the cylindrical portion.
