The dyeing device lowers the pressure inside a closed chamber that closes the periphery of the resin body by a pump. In the state where the adhesion surface of the dyeing base to which the dye is adhered faces the resin body without contact, by heating the dye adhered to the dyeing base inside the closed chamber of which the pressure is lowered, the dye is sublimated, vaporized, and deposited on the resin body. The pressure inside the closed chamber is raised higher than the pressure at the vaporizing and depositing time. By irradiating the resin body on which the dye is vaporized and deposited with electromagnetic wave, the resin body is heated and the dye is and fixed.
