PROBLEM TO BE SOLVED: To provide a double-glazed glass having improved sound insulation performance without deteriorating appearance and look.SOLUTION: In the double-glazed glass 100, a plurality of glass plates G1, G2 are placed opposite to each other through a spacer 4 to form a hollow layer 1 between the glass plates G1, G2, a member 7 for resonance is disposed in the hollow layer 1 in a position a predetermined distance away from the spacer 4, and a cavity 2a, 2b sectioned by the member 7 for resonance, the spacer 4 and the glass plates G1, G2 is formed. The member 7 for resonance has a plurality of through-holes 8 which connects between the hollow layer 1 and the cavity 2a, 2b, and a notched part 2b (second cavity) has been formed on the cavity 2a, 2b side of the member 7 for resonance along the longitudinal direction of the member 7 for resonance. |
