A resin-molded article 10 is formed by injecting molten resin into a molding die from a gate (11). Ribs (61, 62, 63 and 64) having widths larger than that of a thin molded portion (27) in the form of a thin wall are connected one after another from the position of the gate (11) to the thin molded portion (27). Spaces in the molding die for forming the ribs (61, 62, 63 and 64) define a path for the flow of the molten resin and the molten resin injected from the gate (11) flows into a space for forming the thin molded portion (27) through this path at the time of molding the resin-molded article (10). Therefore, the resin can be filled sufficiently for the thin molded portion (27) in the form of a thin wall located distant from the gate (11).
