PROBLEM TO BE SOLVED: To provide a saccharide-binding component detection / measurement system that can detect sugar-binding components such as sugar chain-binding proteins and cells with extremely high sensitivity and can accurately measure the concentration of the components. SOLUTION: A saccharide-fixing fine particle in which a monosaccharide or a saccharide of two or more saccharides is fixed on the surface of a fine particle of a metal or a semiconductor, wherein the metal is selected from gold, platinum, silver and copper. Are cadmium sulfide, titanium oxide, zinc oxide and molybdenum oxide. By detecting the change in optical properties when the saccharide-binding component in the sample solution is bound to the fine particles, the saccharide-binding component is detected and the concentration is measured.
