Abstract:
Provided is a glass cloth whereby there is no need to form a circuit in an inclined arrangement, and a circuit can be formed in which differences in signal transmission speed are reduced. The present invention relates to a glass cloth (1) formed in a long shape by intersecting and weaving warp threads (2) and weft threads (3) comprising glass fibers. The warp threads (2) are curved or inclined so that when an imaginary straight line (L1) is drawn in the longitudinal direction of the glass cloth (1), the number of times that the imaginary straight line (L1) crosses over the warp threads (2) and gaps (S1) between adjacent warp threads (2, 2) is at least two per 100 cm. A gap between the weft threads (3) is 100 µm or less.
