A clutch disc includes a core plate and a friction member having an annular shape. The core plate includes a coupling portion having an annular shape and a plurality of fixation portions. The plurality of fixation portions protrude radially outward from the coupling portion and are circumferentially aligned through a plurality of slits each radially extending between adjacent two of the plurality of fixation portions. The friction member is fixed to the plurality of fixation portions and has an inner diameter larger than a diameter of the core plate at inner peripheral ends of the plurality of slits. The friction member includes a plurality of discharge grooves on an inner peripheral end surface thereof in corresponding portions thereof to the plurality of fixation portions. The plurality of discharge grooves lead water to the plurality of slits when the water drops on the inner peripheral end surface of the friction member.
