A roll type raw material supply device includes a raw material mounting unit for introducing a roll type raw material to which a tape for fixing to the end portion of a raw material is attached; a tape removal unit for clamping a non-bonding portion of the tape and separating the tape from the raw material; and a raw material conveying unit for attaching and moving the raw material. The roll type raw material supply device is capable of automatically and effectively removing the tape attached to a roll type raw material and causing the end portion of the raw material to be moved to a desired location without damage such as warping.
