Abstract
Provided is a microbead analysis method for a microbead. The microbead is formed in a columnar shape having a top surface and a bottom surface facing each other, as placed almost in parallel, and a side surface extending therefrom, and carries an identification pattern formed on at least one of the top surface and the bottom surface and a substance immobilized on a surface thereof having affinity to an analyte substance. The method includes detecting fluorescence emitted from the microbead surface due to interaction of the analyte substance with the substance having affinity to the analyte substance from a region including a region of the top surface and the bottom surface where there is no identification pattern formed and the side surface.
