PROBLEM TO BE SOLVED: To perform an easy, highly quantitative and highly sensitive analysis in immunological analysis using antigen-antibody reaction. SOLUTION: The organic-inorganic composite fine particles for immunologicval analysis are formed of an inorganic core parts and an organic coating parts. In the fine particles the inorganic core parts support a substance having the function of revealing a quantitatively detectable physical quantity, and the physical quantity can be detected from the outside of the particles. Further, a method for producing the fine particles, the fine particles having an antibody or antigen bonded thereto, and an immunological analytic method using the fine particles are proposed.
