摘要：
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 2 , 10.00 to 16.00% by mass of Al 2 O 3 , 17.00 to 25.00% by mass of CaO, 0.01 to 9.50% by mass of TiO 2 , 0.03 to 7.00% by mass of P 2 O 5 , 0.00 to 9.50% by mass of ZnO, 0.00 to 2.00% by mass of SO 3 , 0.01 to 11.50% by mass in total of ZnO and SO 3 , and 0.00 to 2.00% by mass in total of Na 2 O, K 2 O, and LizO, with respect to the total amount. The content SI of SiO 2 , the content A of Al 2 O 3 , the content C of CaO, the content T of TiO 2 , the content P of P 2 O 5 , the content Z of ZnO, and the content SO of SO 3 satisfy the following formula (1): 15.0 ≤ SI / C 2 × A/T × P/ SO + Z 1 / 4 ≤ 690.1
