Zusammenfassung:	A glass composition for glass fiber that has a broad working temperature range and can suppress an elastic modulus difference from that of E-glass fiber. The composition includes 45.60 to 59.00% by mass of SiO2, 0.00 to 8.00% by mass of B2O3, 10.00 to 16.00% by mass of Al2O3, 17.00 to 25.00% by mass of CaO, 0.01 to 9.50% by mass of TiO2, less than 0.03% by mass of P2O5, 0.00 to 9.50% by mass of ZnO, 0.00 to 2.00% by mass of SO3, 0.01 to 11.50% by mass in total of ZnO and SO3, and 0.00 to 2.00% by mass in total of Li2O, Na2O, and K2O, with respect to the total amount. The SiO2 content SI, the B2O3 content B, the TiO2 content T, the ZnO content Z, and the SO3 content SO satisfy the following formula (1).1.79≤(SI/B)×T/(Z+SO)1/4≤122.98(1)
