PURPOSE: To enable the reliable elimination of a master without leaving the master behind, by eliminating the master by transforming the master chemically into a flowing state.
CONSTITUTION: A resin molding tool 1 is constituted in a stratiform state by adhering synthetic resin 3 which is plastic substance for formation of a mold surface to a base 2 made of metal. An uneven pattern obtained by inverting unevenness against that to be applied to a resin product is formed on a mold surface 4 of the synthetic resin 3. To apply the uneven pattern to the mold surface 4 of the synthetic resin 3, unevenness is applied to the mold surface 4 of the synthetic resin 3 by piling up the synthetic resin 3 which is in a flowing state or a soft state and a master 5 having the uneven pattern each other and the master 5 piled up on the mold surface 4 is eliminated by transforming the same chemically into a flowing state.
