Abstract
An electrochemical assay device includes an inner flow passage through which a liquid injected from an inlet flows and a first liquid absorbing material that absorbs the liquid that has passed through the inner flow passage, and is configured to be able to perform an assay based on an electrochemical method. The inner flow passage includes a microflow passage that communicates with the inlet and a separating flow passage provided between the microflow passage and the first liquid absorbing material for separating the liquid inside the inner flow passage into a part to be left in the microflow passage and a part to be absorbed by the first liquid absorbing material when the injection of the liquid is stopped. The electrochemical assay device includes an electrode portion that is disposed inside the microflow passage, a connecting portion that is connected to an external measurement device, and a conducting wire portion that electrically connects the electrode portion to the connecting portion.
