Beschreibung
Zusammenfassung:	The present invention addresses the problem of providing a low-mass glass cloth that, even when impregnated with a resin solution to produce a prepreg that contains, by mass, a low proportion of the glass cloth, can particularly effectively suppress the occurrence of pinholes and longitudinal wrinkles. A glass cloth that has a mass of no more than 10.0 g/m2. The design value Iwd for the gaps between adjacent warp threads is no more than 95 [mu]m, and the design value Ifd for the gaps between adjacent weft threads is no more than 95 [mu]m. The ratio (Iw/If) of the actual value (Iw) of the gaps between adjacent warp threads and the actual value (If) of the gaps between adjacent weft threads is 1.23-1.45. The basket hole area fraction is 12.0%-20.0%.
