Abstract: An ion sensor includes an ion detection element, a reference electrode that provides a reference point of a potential, and a solution in which an ion concentration can be changed in a sensing area of the ion detection element. The sensing area of the ion detection element is disposed in the solution. A method for detecting a target substance employs an ion sensor. The target substance bound to a label having a function of changing the amount of ions detectable by the ion sensor is introduced into the solution, and a change in the amount of ions is detected using the ion sensor.
