Claim:
1. A sensor capable of detecting light, hydrogen gas, and air pressure, comprising: a metal oxide film formed on a surface of an organic film, the metal oxide film produced by a process comprising: wherein the addition polymerizable compound including three or more reactive groups is at least one type of compound selected from the group consisting of trimethylolpropane triacrylate, pentaerythritol triacrylate, pentaerythritol tetracrylate, dipentaerythritol hexaacrylate, pentaerythritol triacrylate isophorone diisocyanate urethane prepolymer, and dipentaerythritol pentaacrylate hexamethylene diisocyanate urethane prepolymer, the addition polymerizable compound including an acid group is at least one type of compound selected from the group consisting of (meth)acrylic acid, vinyl benzenecarboxylic acid, vinyl acetic acid, vinyl sulfonic acid, vinyl benzenesulfonic acid, maleic acid, fumaric acid, an acrylic ester having a phthalic acid group, an acrylic ester having a salicylic acid group, an acrylic ester having an acetylsalicylic acid group, and vinylphenol, the addition polymerizable compound including a hydrophilic functional group is at least one type of compound selected from the group consisting of polyethylene glycol diacrylate, polypropylene glycol diacrylate, glycerin diacrylate, polytetramethylene glycol diacrylate, and 2-hydroxypropyl acrylate, the metal (M1) is potassium or sodium, the metal (M2) is at least one metal selected from the group consisting of indium, zinc and tin, the metal oxide film is formed on the surface of the organic film and contains metal oxide particles that are an oxide of the metal (M2) which ranges in particle diameter from 1 nm or larger to 100 nm or smaller, and the metal oxide film is such that an average particle diameter of the metal oxide particles across a straight line becomes smaller from a surface of the metal oxide film toward the organic film, the straight line being drawn on a longitudinal section of the sensor in parallel with a surface of the substrate or film on which the organic film has been formed and connecting a left edge with a right edge of the metal oxide film.
