The glass roving cloth includes glass rovings each composed of glass filaments, each having a filament diameter Dt of 9.5 to 30.0 μm, bundled in a number bundled Ft of 400 to 8000 as a warp yarn and glass rovings each composed of glass filaments, each having a filament diameter Dy of 9.5 to 30.0 μm, bundled in a number bundled Fy of 400 to 8000 as weft yarns, wherein the weaving density of the warp yarns and weft yarn is 2.0 to 14.0 yarns/25 mm, the average yarn width of the warp yarn and the weft yarn are each 500 to 8000 μm, the widening rate of the warp yarn and the weft yarn are each 3.0 to 30.0%, the glass occupancy in the warp yarn direction is 90.0 to 106.0%, and the glass occupancy in the weft yarn direction is 75.0 to 99.0%.

Glass roving cloth and glass-fiber-reinforced resin sheet

A surface-colored glass cloth including a glass cloth which includes a warp and a weft and a plurality of colored portions which are attached to a surface of the glass cloth is disclosed. One colored portion is disposed in each area including one colored point. An average distance D between the adjacent colored points is 0.50 to 10.00 mm. When the number of warp rows is St, a warp widening degree is Et, the number of weft rows is Sy, and a weft widening degree is Ey in the glass cloth, D, St, Et, Sy, and Ey satisfy a formula: 3.3&#x2264;100&#xd7;D&#xd7;(Et&#xd7;Ey)/(St&#xd7;Sy)&#x2264;25.0.

Surface-colored glass cloth and fiber-reinforced resin molded product

The glass fiber-reinforced resin molded article includes a glass fiber fabric and a transparent resin. The average resin unimpregnation ratio in proximity to filament of the glass fiber fabric is more than 2.0% and 50.0% or less, the warp yarn width Bt and the weft yarn width By of the glass fiber fabric each are from 0.50 to 8.50 mm, the warp yarn weaving density Wt and the weft yarn weaving density Wy of the glass fiber fabric each are from 3.0 to 50 yarns/25 mm, and the degree of widening of warp yarn Et and the degree of widening of weft yarn Ey of the glass fiber fabric each are from 0.70 to 1.10.
