PROBLEM TO BE SOLVED: To provide an immunoassay instrument capable of shortening the measuring time and of more minutely grasping the state of changes due to aging. SOLUTION: Since the change in the intensity of the reflected light of measuring light due to the natural oscillation frequency of a receptor, the ligand in the sample bonded to the receptor and the composite of the receptor and the ligand, which appear in a frequency region lower than the follow-up frequency limit of the ligand, the receptor and the composite of the ligand and the receptor is used, a band of applied external vibration becomes narrower than the conventional bands, applied in order to calculate the follow-up frequency limit, and the measuring time is shortened.
