This disclosure is glass cloth weaved using, as warp and weft, glass yarn including a plurality of glass filaments, with a surface of the glass cloth treated with a surface treatment agent. The glass cloth includes a predetermined region in which the value obtained from the following formula (1) is more than 0 and 0.14 or less: (E1/T1)/(W1/L1), wherein E1 represents second bending stiffness (N · cm2/cm) per unit length in a curvature range of 0.5 to +1.5 cm-1 when bent twice at a curvature of 2.5 cm-1; T1 represents the thickness (cm) of the region; L1 represents the shooting distance (cm) of the warp; W1 represents the warp width (cm); and bending is performed such that the bottom line of the valley generated through bending follows the direction of the weft.
