摘要： Disclosed are a stencil sheet which can smoothly and accurately be perforated even by a small amount of energy while having a required strength and a stencil plate produced from which is easy to control the amount of an ink to be dislocated to an object to be printed and has such an advantage that setoff is small, printability and definition of printed images are excellent, jamming is not caused, and wrinkles are not formed when stencil printing is performed by using the stencil plate; a process for producing the stencil sheet; and a process for producing a stencil plate;
   the stencil sheet comprising a sheet having a large number of minute perforations, the minute perforations being filled with the following resin (A), (B), or (C).

(A) a resin having a melting point lower than that of the sheet
(B) a resin which is soluble in a solvent
(C) a heat adhesive resin
