PROBLEM TO BE SOLVED: To provide a method for manufacturing a thermoplastic porous stamp with open cells using a quite new process instead of a conventionally known process. SOLUTION: First, the surface of a thermoplastic porous stamp material with open cells is masked with a metallic foil to the specified shape, and the part which is not masked is melted/solidified by irradiating the metallic foil with a plasma by a plasma irradiator and thus a non-porous protecting coating film which does not allow oozing of the ink, is formed. At the same time, in the remaining part which is masked, a printing part which allows oozing of the ink, is formed. The method for manufacturing the porous stamp comprises the described steps.
