PROBLEM TO BE SOLVED: To provide a detection sensor detecting easily a physical or chemical property such as the presence of oxygen by visual observation, without requiring a special device such as a photodetector. SOLUTION: This detection sensor has: a porous oxide coating film formed on a metal surface; and a sensitive substance which is deposited on the oxide coating film and generates fluorescence of a wavelength different from a wavelength of fluorescence emitted from the oxide coating film. The oxide coating film is preferably an oxide coating film formed by anodic oxidation in an electrolyte containing oxalic acid. COPYRIGHT: (C)2007,JPO&INPIT
