質は均一であつた。 In addition, when the quality of the glass fibers manufactured using the bushing plates of the example and the conventional example was inspected,
Many of the glass fibers made with the conventional bushing plate were broken midway or had variations in thickness, but the glass fibers made with the bushing plate of the example had such problems. There were no defects, and the dimensional accuracy was high. Furthermore, when the conventional bushing plate is energized as a heating element, the temperature distribution is uneven, resulting in a difference in the viscosity of the molten glass discharged from the nozzle, resulting in uneven quality of the glass fiber obtained. When the bushing plate of the example was energized as a heating element, the temperature distribution was uniform, so the viscosity of the molten glass discharged from the nozzle was constant, and the quality of the obtained glass fiber was uniform.
