A dual-bearing reel includes a reel body, a spool shaft, a pinion gear, a collar member, a bearing, and a sealing member. The reel body includes a bearing housing. The pinion gear is rotatable about the spool shaft. The collar member is mounted on an outer peripheral surface of the pinion gear. The collar member has a large-diameter portion disposed adjacent to a tooth portion of the pinion gear in a shaft direction, and a small-diameter portion having a diameter smaller than the outer diameter of the large-diameter portion. The bearing is housed in the bearing housing and rotatably supports the pinion gear using the collar member. The sealing member is an annular member disposed in contact with the inner peripheral surface of the bearing housing and the outer peripheral surface of the large-diameter portion of the collar member.
