Abstract
A proton conductive film, a method of producing the proton conductive film, and a highly sensitive humidity sensor are provided. The proton conductivity (room temperature, 95% RH) of the proton conductive film is 3×10−21 Scm−1 or more, and the proton conductive film is usable under a neutral-solvent atmosphere. A highly proton conductive polymer film made of an organic/metallic hybrid polymer film including: one or more metal ions selected from a group consisting of Fe ion, Co ion, Ru ion, Zn ion, and Ni ion; and bis(terpyridyl)benzene, is used.
