Abstract

Provided is a glass fiber having a low spinning temperature and a low liquidus temperature, and besides, having a large difference between the liquidus temperature and the spinning temperature, and a method of manufacturing the same. The glass fiber of the present invention includes as a glass composition, in terms of mass % on an oxide basis, 50% to 65% of SiO, 0% to 3% of AlO, 0% to 1% of MgO, 0% to less than 0.7% of CaO, 0% to 1% of LiO, 10% to 20% of NaO, 0% to 2% of KO, 6% to 10% of TiO, and 15% to 20% of ZrO, and has a value for (NaO+KO)/(MgO+CaO) of 6.0 or more.
