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 μm, and the design value Ifd for the gaps between adjacent weft threads is no more than 95 μm. 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%.
