Abstract
The present invention is a low dielectric resin substrate, which is a composite including an annealed quartz glass cloth and an organic resin, where the annealed quartz glass cloth has a dielectric loss tangent of less than 0.0010 at 10 GHz, and tensile strength of 1.0 N/25 mm or more per cloth weight (g/m). This provides a resin substrate that includes a quartz glass cloth which has a low dielectric loss tangent and which is also excellent in tensile strength.
