FIELD: chemistry.
SUBSTANCE: sheet contains base material and a pressure-sensitive layer. End-to-end holes which run from the front surface of the base material to the working surface of the adhesive layer are made in the pressure-sensitive adhesive sheet through laser thermal treatment. The base material used is material which, when heated at a rate of temperature increase of 20°C/min in a nitrogen atmosphere, temperature at peak thermal decomposition where thermal decomposition of this material is maximum does not exceed 450°C, and the difference between the peak thermal decomposition temperature of the base material and the melting peak temperature does not exceed 250°C. The base material is a film based on a synthetic resin, a foamed film or a laminated film.
EFFECT: prevention of capture of air and therefore prevention of formation of bubbles after gluing the sheet.
