Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a smell measuring method and its instrument for accurately measuring the kind of smell (fragrance quality). SOLUTION: According to this smell measuring method and its instrument, a smell to be measured is measured based on the size and inclination of a vector in a two-dimensional coordinate system having, as elements of coordinate axes different from each other, measurement values of detection signals of a plurality of smell sensors 106A and 106B with reaction characteristics to smells different from each other. Data on time change of at least one of the size and inclination of the vector are used to specify the kind of smell (fragrance quality) to be measured. COPYRIGHT: (C)2004,JPO&NCIPI
