Zusammenfassung:PROBLEM TO BE SOLVED: To obtain an original paper for heat-sensitive stencil printing by which mechanical strengths of the original paper for the heat-sensitive stencil printing in which a porous film is used as a substrate are improved and carrying qualities in a printing machine are improved and there exists no generation of white spot and no ink stain is generated on the underside of a printed article and excellent quality of printing can be obtained. SOLUTION: In the original paper for heat-sensitive stencil printing prepared by sticking together a heat-sensitive film and a porous substrate, the porous substrate has a constitution in which porous films prepared of a W/O type emulsion consisting of a solution in which a synthetic resin ingredient is dissolved in a solvent as a continuous phase and a water phase as a discontinuous phase are laminated by at least two layers.
