Zusammenfassung:To provide a light transmissive conductive film and a light control film having good thermal stability and capable of reducing the variation in light control function.SOLUTION: There is provided a light transmissive conductive film 1 having a light transmissive base material 2 and a light transmissive conductive layer 3. The light transmissive conductive layer 3 has a crystalline region and an amorphous region. The maximum length of crystal grains in the light transmissive conductive layer 3 is 200 nm or less and when the light transmissive conductive layer 3 is heated under the conditions at 80°C for 240 hours in the atmosphere, the maximum length of crystal grains is 200 nm or less.SELECTED DRAWING: Figure 1 【課題】熱安定性が良好であり、調光機能のばらつきを低減することができる光透過性導電フィルムおよび調光フィルムを提供する。【解決手段】本発明の光透過性導電フィルム1は、光透過性基材2と、光透過性導電層3とを備える。光透過性導電層3は、結晶質領域および非晶質領域を有する。光透過性導電層3における結晶粒の最大長は200nm以下であり、光透過性導電層3を大気雰囲気で80℃、240時間の条件で加熱した際における結晶粒の最大長は、200nm以下である。【選択図】図1
