PROBLEM TO BE SOLVED: To hold a surface roughness of a mold release agent layer and an accuracy of a surface shape in the same degree as those of a mold surface and to form the layer without reducing a production efficiency by spraying gas to a surface of a mold before molding a resin and forming the layer. SOLUTION: Since gas is sprayed to a surface of a mold to form a mold release agent layer of an extremely thin gas component or the like is formed, a surface roughness of the layer and an accuracy of a surface shape can be held in the same degree as that of the surface of the mold. Since the step of spraying the gas is a step of simply completing in a short time, the step can be assembled in the step of molding a resin. Since a force (mold release force) necessary in the case of releasing a resin molding or a resin connecting type member is reduced, a surface roughness of the layer formed on the surface of the mold and an accuracy of the surface shape can be held in the same degree as that of the mold, and the layer can be easily formed during manufacturing step without lowering a production efficiency. |
