    • A stamp includes an ink supply member capable of exchangeably affixing an engraved thermal stencil paper which is engraved by means of a thermal head, and a stamp holder wherein the engraved thermal stencil paper attached to the ink supply member is received so as to oppose the stamping opening. The thermal stencil paper is constructed by layering a film which melts with heat and a porous supporting member. The ink supply member is constructed by impregnating an open-pored microporous structure with ink having a viscosity of 1,000 to 100,000 CPS and 2.5 or less on the Thixotropy Index. The thermal stencil paper, along with a transport-assistant tape to reinforce the thermal stencil paper, are rolled onto a core in a double layer. Stamping quality can be further improved by providing the thermal stencil paper with a water-repellent oil-repellent layer, by making the microporous structure impermeable to ink on surfaces other than the surface in contact with the thermal stencil paper, or by rolling the thermal stencil paper onto the core without an adhesive agent.
