A pressure-sensitive adhesive tape or sheet having a pressure-sensitive
adhesive layer formed on at least one surface of the support thereof,
wherein the surface of the pressure-sensitive adhesive layer on at least
one surface of the support partly has projected spots of fibers. The
projected spots of fibers are preferably raised spots of fibers that are
raised from the surface of the pressure-sensitive adhesive layer. The
pressure-sensitive adhesive tape or sheet is favorable for flooring
material fixation. The pressure-sensitive adhesive tape or sheet is
produced according to a flocking method that comprises flocking the
surface of the pressure-sensitive adhesive layer on at least one surface
of the support to thereby form projected spots of fibers partly in the
surface of the pressure-sensitive adhesive layer.
