VACUUM MULTILAYER GLASS, SEALING MEMBER, AND METHOD FOR MANUFACTURING VACUUM MULTILAYER GLASS

摘要

A vacuum multilayer glass configured by layering a first and second glass substrate with a gap therebetween, the gap being in a low pressure state less than the atmospheric pressure, characterized in that: said gap is sealed with a sealing member; said sealing member comprises a metal member and a vitrification layer for joining the metal member and the glass substrates; and said metal member is selected from among materials that satisfy the requirement Y>=0.10X [wherein X represents tensile strength (N/mm2) and Y represents breaking elongation (%)], when being maintained in the atmosphere at 490°C for 40 minutes and then subjected to a room temperature tensile test at a tensile speed of 1 mm/min.
