PROBLEM TO BE SOLVED: To provide a high-temperature fire-resistant foam insulator which, in the event of fire, does not burn with smoke and flame and also bears up under a high temperature and is capable of keeping heat insulation performance. SOLUTION: This high-temperature fire-resistant glass fiber, keeping its shape at around 1,000°C even in the event of fire when it receives heat by far exceeding the glass melting temperature, is produced by forming a heat resistant coating 6 on the surface of a glass fiber 5 by immersing magnesium chloride 4 as a high-temperature heat-resistant treating agent 3 in the space among fibers of a glass fiber 1 or a glass wool 2 in which ultra thin glass fibers are closely packed.
