B's analogy is S r; Pb0 72 times called n3, Or+ 5i02 26, 0 1.7 As20. 0.3 j! High dielectric constant glass fibers were manufactured using the ``I'' structure.9 However, if optical high lead glass with a high dielectric constant is used as a raw material, melt spinning is possible, easy cutting, and a single circuit printing process that reduces work efficiency. There were several issues that needed to be solved as high dielectric constant glass fiber for substrates. Specifically, the tensile strength of the fiber itself is low, causing problems such as glass filaments breaking during weaving, resulting in fuzz on the surface of the fabric and deterioration of the working environment. In addition, when weaving woven fabrics, it is necessary to remove the sizing agent applied to the surface by heat treatment to protect it during weaving of glass fibers, but since the glass transition temperature is low at 420C, the fiber strength increases at high temperatures. Because of this problem, it is necessary to lower the processing temperature and heat for a long time. In addition, it has poor chemical durability, especially water resistance, and when made into a laminate, it may cause insulation failure.
［発明か解決しようとする課題］ 本発明は、原料の溶融ガラスの紡糸性かよく。[Invention or problem to be solved] The present invention improves the spinnability of the raw material molten glass.

If it is less than 80% by weight, a high dielectric constant cannot be obtained, and if it is more than 80% by weight, the strength, water resistance and heat resistance will be low, and the spinnability will also be poor. A more preferred range is 72-76% by weight.
