Method of manufacturing molded article

A method of manufacturing a molded article for manufacturing an integrally molded article including a first molded article, a second molded article, a third molded article, and a fourth molded article by using a fixed mold which is fixed and a movable mold which is movable, the method comprising:

• a first molding step of causing the first molded article held by the fixed mold to face the second molded article held by the movable mold, closing the molds, and molding a first intermediate integrally molded article by joining the first molded article to the second molded article by pouring a molten resin into a space formed by the first molded article and the second molded article;
• a second molding step of causing the first intermediate integrally molded article held by the movable mold to face the third molded article held by the fixed mold, closing the molds, and molding a second intermediate integrally molded article by joining the first intermediate integrally molded article to the third molded article by pouring the molten resin into a space formed by the first intermediate integrally molded article and the third molded article;
• and
• a third molding step of causing the second intermediate integrally molded article held by the fixed mold to face the fourth molded article held by the movable mold, closing the molds, and joining the second intermediate integrally molded article to the fourth molded article by pouring the molten resin into a space formed by the second intermediate integrally molded article and the fourth molded article.
