(ガラスフィルムの用意)
厚みが100μmのガラスフィルムロールを用意した。
(第1インジウム系導電性酸化物層(第1酸化物層)の形成)
次いで、ガラスフィルムロールを真空スパッタ装置に設置して、未搬送時の気圧が4×10-3Paとなるまで真空排気した(脱ガス処理)。この時、スパッタリングガス(ArおよびO2)を導入しない状態で、ガラスフィルムの一部を搬送し、2×10-2Paまで気圧が上がることを確認した。これにより、ガラスフィルムロールに十分な量のガスが残存していることを確認した。
次いで、ガラスフィルムロールを繰り出しながら、ガラスフィルムの上面に、スパッタリングにより、非晶質ITOからなり、厚みが40nmである第1インジウム系導電性酸化物層を形成した。具体的には、ArおよびO2を導入した気圧0.3Paの真空雰囲気下(流量比はAr:O2=100:1.4)で、直流(DC)電源を用いて、12質量%の酸化スズと88質量%の酸化インジウムとの焼結体からなるターゲットをスパッタリングした。
(金属層の形成)
Ag-Cu合金からなり、厚みが8nmである金属層を、スパッタリングにより、第1インジウム系導電性酸化物層の上面に形成した。具体的には、Arを導入した気圧0.3Paの真空雰囲気で、電源として、直流(DC)電源を用い、Ag合金(三菱マテリアル社製、品番「No.317」)をスパッタリングした。
(第2インジウム系導電性酸化物層(第2酸化物層)の形成)
非晶質ITOからなり、厚みが38nmである第2インジウム系導電性酸化物層を、金属層の上面に、スパッタリングにより、形成した。具体的には、ArおよびO2を導入した気圧0.4Paの真空雰囲気下(流量比はAr:O2=100:1.5)で、直流(DC)電源を用いて、12質量%の酸化スズと88質量%の酸化インジウムとの焼結体からなるターゲットをスパッタリングした。
上記の操作により、ガラスフィルムの上に、順に、第1インジウム系導電性酸化物層、金属層および第2インジウム系導電性酸化物層が形成された光透過性導電ガラスフィルムを得た。
得られた光透過性導電ガラスフィルムを、大気雰囲気下で140℃、30分の条件で、加熱した。
第1インジウム系導電性酸化物層の厚みを30nmとし、金属層および第2インジウム系導電性酸化物層を形成しなかったこと以外は、実施例1と同様にして、光透過性導電ガラスフィルムを得た。
第1インジウム系導電性酸化物層の厚みを100nmとし、金属層および第2インジウム系導電性酸化物層を形成しなかったこと以外は、実施例1と同様にして、光透過性導電ガラスフィルムを得た。

(3)応答性
実施例および比較例で得られた光透過性導電ガラスフィルムを用い、下記のようにして、500×500mmのEC調光素子を製造した。得られたEC調光素子に電流を流し、EC調光層の色彩が変化する時間を測定した。EC調光層の色彩が変化する時間が60秒以内の場合を〇と評価し、60秒より長い場合を×と評価した。
(EC調光素子の製造)
実施例1で得られた光透過性導電ガラスフィルムを2枚準備し、これらをEC調光素子の上側電極基板および下側電極基板として用い、EC調光素子を製造した。具体的には、市販のEC調光層(エレクトロクロミック化合物層/電解質層/エレクトロクロミック化合物層)の両面に、光透過性導電ガラスフィルムを積層し、EC調光素子を製造した。
