Abstract

In an electrochemical lateral flow immunological test method, flow of a sample solution is controlled. As a result, the reaction time is short and quantitative measurements and electrical measurements can be performed with excellent sensitivity and high accuracy, and the invention provides a sensor employed in the method. Electrode portions, electrically conductive portions for transferring electric current from the electrode portions, and connecting portions connected to an electrical measuring instrument for measuring the electric current values are arranged on a supporting body including a resin sheet, pads and the like disposed by partial lamination on the supporting body. A sample solution flows over the plurality of pads, and electrochemical detection is performed by controlling the flow at the position of the electrode portions. Furthermore, the flow is controlled by a flow rate control pad, a flow passage portion fiber pad, and flow rate control protruding portions.
