PROBLEM TO BE SOLVED: To provide a molding device which can effectively extract gas form a cavity without using a degassing implement and suppress the occurrence of a wall-lacking part in a molding. SOLUTION: An opening/closing mold comprising an upper mold 12 and a core mold 14 is connected openably/closably with a lower mold 11. Degassing holes 16 and 18 opening outward are formed in the parting plane of each mold 11, 12, or 14. Degassing channels 17, 19, and 20 are formed in molding surfaces forming the cavity C, especially in the molding surfaces 12a and 14a of the upper mold 12 and the core mold 14 which are arranged on the upper side while being closed to communicate with the degassing holes 16 and 18.
