ENVIRONMENT MEASURING ELEMENT AND ENVIRONMENT MEASURING METHOD USING IT

摘要

PROBLEM TO BE SOLVED: To provide an environment measuring element constituted so as to be capable of evaluating an environment rapidly and inexpensively. SOLUTION: The environment measuring element is constituted of a substrate and the thin film formed on the surface of the substrate. The thin film contains two or above kinds of metals different in reactivity corresponding to the kind of gas and is continuously or intermittently different in composition at every position on the surface of the substrate and different in hue after reaction corresponding to the composition and the kind of a gas to be reacted.
