摘要：
A glass composition for glass fiber includes SiO2 in the range of 52.0% by mass or more and 56.0% by mass or less; B2O3 in the range of 21.0% by mass or more and 24.5% by mass or less; Al2O3 in the range of 9.5% by mass or more and 13.0% by mass or less; MgO in the range of 0% by mass or more and less than 1.0% by mass; CaO in the range of 0.5% by mass or more and 5.5% by mass or less; SrO in the range of 0.5% by mass or more and 6.0% by mass or less; and TiO2 in the range of 0.1% by mass or more and 3.0% by mass or less; and includes F2 and Cl2 in the range of 0.1% by mass or more and 2.0% by mass or less in total, with respect to the total amount.
