SOLUTION: A light-modulating member 20 comprises a pair of transparent substrates 21, 22, a light-modulating cell 30 disposed between the pair of transparent substrates 21, 22, and two joint layers 23, 24, disposed between the transparent substrates 21, 22 and the light-modulating cell 30, for joining the transparent substrates 21, 22 and the light-modulating cell 30 together. The light-modulating cell 30 can adjust a visible light transmittance by electronic control. The storage elastic modulus of the joint layers 23,24 is 6×10Pa or less at 1°C to 30°C inclusive.EFFECT: It is possible to suppress a local discoloration in a light-modulating member.SELECTED DRAWING: Figure 2

    【解決手段】調光部材20は、一対の透明基材21,22と、一対の透明基材21,22の間に配置された調光セル30と、透明基材21,22と調光セル30との間に配置され、透明基材21,22と調光セル30とを接合する2つの接合層23,24と、を備える。調光セル30は、電子制御により可視光透過率を調節可能である。接合層23,24の貯蔵弾性率は、1℃以上30℃以下で、6×106Pa以下である。【効果】調光部材における局所的な変色を抑制することができる。【選択図】図2
