<p>The present invention provides a heat-sensitive stencil sheet comprising a thermoplastic resin film of constant smoothness laminated on a substrate even when the sheet is wound up into a roll or is stacked with another sheet for a long period of time, which provides excellent printing images by preventing deterioration of susceptibility to perforation by a thermal head. The heat-sensitive stencil sheet contains a thermoplastic resin film laminated onto a porous substrate, in which PPS surface smoothness of the surface of the porous support of the stencil sheet is 1.2 mu m or less as measured while a film having PPS surface smoothness of 0.0 mu m and a thickness of 0.1-10 mu m is pressed against the surface of the porous support. Preferably, the PPS surface smoothness of another surface of the porous support to be laminated with a thermoplastic resin film is 0.9 mu m or less as measured while a film having PPS surface smoothness of 0.0 mu m and a thickness of 0.1-10 mu m is pressed against the other surface of the porous support.</p> |
