PROBLEM TO BE SOLVED: To detect an antigen or antibody contained in a sample to be analyzed with high accuracy.SOLUTION: In the disk 100 for sample analysis for measuring with optical read means an amount of beads 110 for a marker where biopolymers fixed to a track region 105 having a groove structure comprising a groove 107 or a land 108 on the disk surface or a structure provided with a pit 109 are combined, a diameter of the bead 110 for a marker is smaller than width of the groove 107 or the pit 109 and is large enough to allow only one bead to be placed in the width direction of the groove 107 or the pit 109. |
