A printing sheet used in a stamp includes a porous layer in which ink can be impregnated and a fibrous layer provided to a side of the porous layer opposite to the pattern. The porous layer carries a pattern on a surface thereof, the pattern including a non-print portion which blocks the permeation of the ink and a print portion which allows the permeation of the ink. The fibrous layer prevents the deformation of the porous layer. The fibrous layer is so constituted that ink can be impregnated therein.
