摘要：
An impedance sensor for detecting a mixing ratio of a liquid or a gas includes a substrate, at least a pair of electrodes, and a protective film. The substrate is configured to be disposed in the liquid or the gas. The pair of electrodes is disposed on the substrate. The protective film is disposed on the substrate so as to cover the pair of electrodes. The protective film is made of a material having a relative permittivity greater than or equal to 6.
