PROBLEM TO BE SOLVED: To enable manufacture of a globe for an electric bulb which is comfortable for the eyes and low cost. SOLUTION: In this method for molding, a parison for an insert being molded of first resin and having a gate hole formed in a prescribed place is set in a cavity mold and a cavity space is formed by opposing a core mold to the cavity mold. A double-layer parison is molded by filling the cavity space with second resin through the gate hole. Then, the core mold is opposed to a blow mold and compressed air is blown in so as to inflate the double-layer parison. By molding a globe 12 for an electric bulb with the first resin colored more deeply than the second resin, it is made comfortable for the eyes, since the front part 52 of the globe 12 for the electric bulb is colored deeply. |
