| abstract | 【Task】 To provide a glass cloth in which the bending is suppressed while the thickness is maintained at 16 μm or less. Moreover, the present invention provides a prepreg and a printed wiring board in which a difference in signal propagation speed between a plurality of transmission lines is reduced. [Solution] A glass cloth having a thickness of 8 μm or more and 16 μm or less, which is formed by weaving glass yarns composed of a plurality of glass filaments as warps and wefts, Formula (1); Y = F / (25000 / G) × 100 (1) (In the formula, F is the weft yarn width (μm), and G is the weft weave density (lines / 25 mm).) The ratio Y of the weft yarn in the longitudinal direction, which is obtained in the above, is 75% or more and 90% or less, A glass cloth having a sum of a warp yarn width and a weft yarn width of 380 μm to 500 μm. [Selection figure] None |
