To provide a tape winding device capable of automatically winding a remaining odd tape in the added state.

Roll bodies R1, R2 of the odd cut tapes T1, T2 are set to a roll support part 5 and a rotor 6 respectively, and the end parts of the cut tapes T1, T2 drawn out of the respective roll bodies R1, R2 are jointed by sticking a pressure sensitive adhesive double coated tape piece T3 bonded to the adhesive face side. A transfer path of the cut tapes T1, T2 is provided with a movable guide roller 8 reciprocated in the axial direction of the rotor 6. The rotor 6 is rotated in one direction by a motor 13, and the movable guide roller 8 is reciprocated to spirally wind the cut tape T1 drawn out of one roll body R1, in order by the other roll body R2 rotated together with the rotor 6.
