PROBLEM TO BE SOLVED: To provide a detection method capable of measuring with high reliability when detecting a target of detection in a sample solution. ! SOLUTION: The detection method comprises: a step for supplying a sample solution including a target of detection to one side of a crystal resonator 4, with respect to the crystal resonator 4 in which an adsorption layer 46 for adsorbing the target of detection is formed on the surface of an electrode 42 on one side; a step for supplying a liquid including a first bead group 45 coupled with the target of detection to one side of the crystal resonator 4; and a step for subsequently supplying a liquid including a second bead group 47 including particles whose diameter is smaller than that of the particles in the first bead group 45 to one side of the crystal resonator 4. By the step for supplying the second bead group 47, the second bead group 47 enters a gap between the first bead group 45 and the surface of the crystal resonator 4, and the first bead gr |
