PURPOSE:To produce a tacky tape having less kink and curl in a high yield, by preparing a tacky sheet by a process comprising heat treatment of a particular cloth base material and providing the material with a tacky layer and cutting the sheet so as to have a small width and converting the cut sheet into a wound form. CONSTITUTION:A cloth base material 1 is prepd. by forming, on a woven fabric 3 (a) comprised of multiple filaments of a synthetic fiber (e.g., PP fiber) having a heat shrinkage ratio difference, in absolute value, between warp and weft strands of up to 6% at 80-180 deg.C and preferably having a total size of 30-200 de, a laminate layer 2 (b) of 30-100g/m<2> comprised of a synthetic resin (e.g., PE), which layer has a heat shrinkage ratio difference from that of the weft strands of the fabric (a), in absolute value, of up to 6%. The base material 1 is heat treated at a temp. ranging from the max. treatment temp. at the subsequent adhesion processing step to a temp. about 20 deg.C higher than the max. temp. Thereafter, a soln. type tacky adhesive is applied and dried, thereby providing the base material with a tacky layer 5. If desired, a release agent layer 4 is further provided to prepare a tacky sheet. This sheet is cut so as to have a small width and converted to a wound form to prepare a tacky tape.
