Abstract

Provided is a glass composition for glass fiber that suppresses variations in fiber diameter of glass fiber including 45.60 to 59.00% by mass of SiO, 10.00 to 16.00% by mass of AlO, 17.00 to 25.00% by mass of CaO, 0.01 to 9.50% by mass of TiO, 0.03 to 7.00% by mass of PO, 0.00 to 9.50% by mass of ZnO, 0.00 to 2.00% by mass of SO, 0.01 to 11.50% by mass in total of ZnO and SO, and 0.00 to 2.00% by mass in total of NaO, KO, and LiO, with respect to the total amount. The content SI of SiO, the content A of AlO, the content C of CaO, the content T of TiO, the content P of PO, the content Z of ZnO, and the content SO of SOsatisfy the following formula (1):15.0≤(SI/C)×(A/T)×{P/(SO+Z)}≤690.1  (1).
