PURPOSE: A mold are provided which are inexpensive, and which constantly disperse pulp to obtain product having uniform thickness, and a manufacturing method of the mold is provided. CONSTITUTION: The manufacturing method of mold for pulp mold comprises a metal bead preparation process of preparing aluminum bead, copper bead, aluminum based alloy bead, copper based alloy bead or phosphor bronze as a material for manufacturing the mold for pulp mold; a grain size sorting process of sorting the prepared bead to grain diameter of 1 to 5 mm after selecting grain size of the material according to characteristics of a product to be molded; a mock-up processing process; a shape forming process of forming shape of the material using a mock-up having certain shape; a sintering process of completing shape of the material by sintering the shape formed material of the metal bead or a mixture of the metal bead and binder having adhesive force in a sintering furnace and controlling size of pores through a means for properly controlling sintering temperature and time, wherein the pores are formed on the bead by melting only a surface part of the bead during sintering; and an airtightness maintenance processing process for obtaining shape stability of the material using organic binder having adhesive force and blowing air of high temperature onto the bead so that the beads are connected to each other to obtain a mold having thickness of 5 to 15 mm.
