摘要：
Glass fibers having non-circular cross sections, excellent strength and excellent modulus of elasticity, and a fiber-reinforced resin compact using the same are provided. The glass fibers having non-circular cross sections are obtained by spinning the molten glass prepared by melting a glass composition as a raw material for the glass fibers. The glass fibers have a composition in which the content of SiO 2 is 57.0 to 63.0% by mass, the content of Al 2 O 3 is 19.0 to 23.0% by mass, the content of MgO is 10.0 to 15.0% by mass and the content of CaO is 5.5 to 11.0% by mass, in relation to the total amount of the glass fibers, and the ratio of the content of MgO to the content of CaO, MgO/CaO falls within a range from 0.8 to 2.0.
