Provided is a glass fiber-reinforced resin molded article having high tensile strength and high impact strength in combination with a low dielectric constant and a low dissipation factor. The glass fiber-reinforced resin molded article contains: 10 to 90 mass% of a glass fiber; and 90 to 10 mass% of a resin based on the total amount of the glass fiber-reinforced resin molded article, wherein the glass fiber has composition containing: 52.0 to 57.0 mass% of SiO2; 13.0 to 17.0 mass% of Al2O3; 15.0 to 21.5 mass% of B2O3; 2.0 to 6.0 mass% of MgO; 2.0 to 6.0 mass% of CaO; 1.0 to 4.0 mass% of TiO2; and less than 1.5 mass% of F2, and the total amount of Li2O, Na2O, and K2O is less than 0.6 mass%, based on the total amount of the glass fiber, and the glass fiber has a number-average fiber length of 30 to 5000 µm.
