Abstract: Provided is a glass fiber-reinforced resin molded article with high mechanical strength and in which occurrence of undispersion of glass fiber is suppressed. In the glass fiber-reinforced resin molded article, glass fiber includes a flat cross-sectional shape having a minor axis D1 in the range of 3.0 ?m or more and 10.5 ?m or less and a major axis D2 in the range of 11.0 ?m or more and 29.0 ?m or less, the number average fiber length L (?m) of the glass fiber included in the glass fiber-reinforced resin molded article is in the range of 195 ?m or more and less than 400 ?m, the glass fiber content C (wt %) in the glass fiber-reinforced resin molded article is in the range of more than 50.0 wt % and 80.0 wt % or less, and the D1, D2, L, and C satisfy the following formula (1): 1200.0?C×L2/(D1×D22)?2550.0 ??(1).
