An object is to improve a spool that is formed of prepreg sheets. In accordance with one aspect, the spool (10) is installed in a fishing reel and including a spool body (11) having a frusto-conical shell (13) around which a fishing line is wound. The shell is formed by heat pressing a laminate including a plurality of body sheets (21-24, 31, 32) rolled one over another. The body sheets have the same arcuate shape and the same fiber orientation (SF). The body sheets are rolled in the same direction to form a frusto-conical shape. The joints (21a-24a, 31a, 32a) where both ends of the body sheets overlap with each other are arranged at regular intervals in the circumferential direction of the shell (13).
