<p>PURPOSE:To prevent exfoliation between a substrate and a film and between films due to an effect of the outside such as moisture and thereby to make the durability and reliability of a sensor excellent. CONSTITUTION:A sensor film 12 containing a chemical-material-sensitive compound is provided on a substrate 11. The sensor film 12 may be either a single- layer film or a laminate with a dyestuff film, and the contact of the sensor film 12 with a chemical material to be inspected results in a change in a light reflectance. Thereby the chemical material is detected and determined. A sealing film 15 is provided for the lateral outer-peripheral end faces of the substrate and the sensor film.</p> |
