A continuous casting roll comprises a roll body having a cooling water bore coaxially therewith, and a sleeve fitted around the roll body and having one end fixed to the roll body and the other end as a free end. The roll body has a trunk portion and a shaft portion at each end of the trunk portion. A plurality of cooling water channels provided between the trunk portion and the sleeve extend in parallel axially thereof and have opposite ends in communication with the water bore. The sleeve is fitted around the roll body by a shrink fit the interference of which decreases steadily from the fixed end toward the free end to permit free thermal deformation of the sleeve toward the free end.
