Abstract: There is provided a multi-layered glass in which two glass plates are placed such that they form a space via a spacer placed in a peripheral part of glass plates, wherein at least one low-emissivity film, which includes a plastic film and a Fabry-Perot interference filter formed on one side or both sides of the plastic film, is placed in the space, whereby space is divided; each of gaps between the glass plates and the spacer, and between the low-emissivity film and the spacer is sealed with a primary sealing material; a gap between the glass plates outside of the primary sealing material and the spacer is sealed with a secondary sealing material; and a reinforcement material is placed inside of the secondary sealing material. The multi-layered glass has a good appearance and excellent heat-insulating properties.
