To provide a double-glazed glass unit in which a double-glazed glass can be properly held against warping of the double-glazed glass due to temperature difference, and a double-glazed glass for use in the double-glazed glass unit.SOLUTION: A double-glazed glass unit comprises: a double-glazed glass 10 comprising, a first glass plate 11, a second glass plate 12, a sealing material and a spacer: a frame body 20 facing a peripheral edge 8 of a first plane 31 of the first glass plate 11 and a fourth plane 34 of the second glass plate 12, and holding the first and second glass plates 11, 12; and a sealing section 24 sealing a gap between the first plane 31, the fourth plane 34 and the frame body 20. The sealing section 24 has: a first sealing area 41 which faces corner portions 8a of the peripheral edges 8 of the first and fourth planes 31, 34; and a second sealing area 42 which faces a side portion 8b sandwiched by two corner portions 8a out of the peripheral edges 8 of the first and fourth planes 31, 34. An elastic modulus of the second sealing area 42 is smaller than an elastic modulus of the first sealing area 41.SELECTED DRAWING: Figure 3 【課題】温度差等による複層ガラスの反りに対して複層ガラスを適正に保持可能な複層ガラスユニット及びこの複層ガラスユニットに用いられる複層ガラスを提供する。【解決手段】第１ガラス板１１と、第２ガラス板１２と、封止材と、スペーサーと、を有する複層ガラス１０を備えると共に、第１ガラス板１１の第１面３１及び第２ガラス板１２の第４面３４の周縁８に対向し、第１ガラス板１１及び第２ガラス板１２を挟持する枠体２０と、第１面３１及び第４面３４と枠体２０との間の隙間を封止するシール部２４と、を備え、シール部２４は、第１面３１及び第４面３４の周縁８の角部８ａに対向する第一シール領域４１と、第１面３１及び第４面３４の周縁８のうち２つの角部８ａに挟まれた辺部８ｂに対向する第二シール領域４２とを有し、第二シール領域４２の弾性率が第一シール領域４１の弾性率よりも小さい。【選択図】図３
