Abstract

A molding die includes a die having a mold plane; and gloss control granules composed of 50 to 80 pbw of a shape retention fixation base material such as a thermosetting resin; 30 to 80 pbw of a diffuse reflecting surface formation core material such as a ceramic powder; and 5 to 10 pbw of a roughness enhancement material such as an inorganic fiber, adhered to the mold plane in a spaced-apart manner. The gloss control granules are each independently adhered in the spaced-apart manner to form gloss control projections on the mold plane of the die so that a surface of a molded product molded on the die forms a surface having a small specular reflection or a diffuse reflection, and the gloss control projections having fine, uneven surfaces with recesses and projections are formed on the mold plane at a coating rate of 40 to 80%.
