PROBLEM TO BE SOLVED: To provide a method for forming a non-ink-oozing non-porous protective film, which is obtained by fusing and solidifying the section of a thermoplastic porous stamping material having open cells after being cut not by the conventionally known method but by a new method. SOLUTION: In this manufacturing method for a porous stamp, the non-ink-oozing non-porous protective film is formed by cutting the thermoplastic porous stamping material having open cells by a laser beam and then fusing and solidifying the section as a means for solving the problem.
