  • Publication number: 20210191011
    Abstract: A radio-wave transmitting substrate includes a dielectric substrate, and, on at least one main surface of the dielectric substrate, a heat-ray reflection film including an electroconductive film, and an opening where the electroconductive film is absent in a plan view. At least a part of the at least one main surface in a plan view is a radio-wave transmitting region. The radio-wave transmitting region is a region where every 1-cm square unit region in the region satisfies the following expression (a): L>802.6×S?503.7. L is an overall length (unit: mm/cm2) of a boundary between the heat-ray reflection film and the opening in the unit region, and S is a proportion of an area occupied by the heat-ray reflection film in the unit region.

  • Publication number: 20180170795
    Abstract: A glass includes, in mass percentage on an oxide basis, 50 to 85% of SiO2, 0 to 10% of B2O3, 1 to 20% of Na2O, and 20% or less of K2O, and Sb2O3 is substantially not contained. A total content (Ni+Cr) is more than 0 ppm by mass and 1.2 ppm by mass or less. A total iron oxide (t-Fe2O3) in terms of Fe2O3, a ratio (Na2O/Al2O3) and a total content (Al2O3+K2O) fall within specific ranges, respectively. The contents of each component satisfy a specific relationship.
