PROBLEM TO BE SOLVED: To inhibit the reduction in soundproof performance in the resonance frequency region of each of glass plates from being caused, which reduction is an inconvenient point of a conventional sealed double-glazed unit. SOLUTION: This unit has an assembled rectangular lattice that comprises cylindrical lattice members 6 each of which consists of a hollow cylinder having a thin thickness and is placed within the internal space 4 of the unit so as not to be in contact with any of glass plates 2, wherein plural through-holes 8 and 8' or slits are formed in main member parts each being opposite to one of glass plates 2, and/or the side member parts of each of the cylindrical lattice members 6, respectively and also, a reinforcing part 9 for increasing compression-resistant strength in the direction of the normal to each of the main faces being opposite to the glass plates 2, is placed in each of the cylindrical lattice members 6. |
