<P>PROBLEM TO BE SOLVED: To enhance the reproducibility of the sensitivity and the response of a taste sensor by solving at least several of problems when a lipid film or a silicon nitride film is used in the taste sensor for sensing by using an SPV method. <P>SOLUTION: The taste sensor includes a semiconductor substrate 10, and an inorganic film 2 formed on the semiconductor substrate as an assembly of particles made of a metal oxide and having different particle sizes. A method for sensing the taste by the taste sensor includes a step of sensing the concentration of a substance by bringing an aqueous solution 48 to be sensed into contact with the inorganic film 2, and a step of manufacturing the inorganic film 2 by a plasma flame coating method. A method for sensing the quantitative determination of a taste inductive substance uses this taste sensor. <P>COPYRIGHT: (C)2004,JPO |
