Abstract
A carrier glass of the present invention is a carrier glass for carrying an organic resin substrate, wherein the carrier glass has a flat sheet shape having a thickness of from 0.1 mm to 1.2 mm, wherein the carrier glass has a content of iron in glass in terms of Fe2O3 of from 45 ppm by mass to 130 ppm by mass, and wherein the carrier glass has a transmittance at a wavelength of 308 nm in a thickness direction of from 71% to 81%.
Claims17
A carrier glass for carrying an organic resin substrate,
- wherein the carrier glass has a flat sheet shape having a thickness of from 0.1 mm to 1.2 mm,
- wherein the carrier glass has a content of iron in glass in terms of Fe2O3 of from 45 ppm by mass to 130 ppm by mass,
- wherein the carrier glass has a transmittance at a wavelength of 308 nm in a thickness direction of from 71%to 81%,
- wherein the carrier glass has a ratio of (MgO+CaO+SrO+BaO)/Al2O3 in terms of mass % of from 0.90 to 1.40,
