PROBLEM TO BE SOLVED: To dispense with binding/free separating operation and enable manufacture at a low cost, using simple detection in a device for detecting a substance to examined in a liquid sample. SOLUTION: This detection device is provided with a reaction tank 1 and an absorber 2, which are connected to each other through a passage 3. While a liquid sample is added, the liquid sample and a marker component dissolved therein are discharged gradually to the outside of the reaction tank 1 through the passage 3. When a substance to be examined exists in the liquid sample, the addition of the liquid sample to the reaction tank 1 causes an antigen- antibody reaction between the marker component held in the reaction tank 1 and the substance to be examined. The substance to be examined that is bonded to the marker component reacts with a fixed component that is fixed in the reaction tank 1. The reaction progresses concurrently with the discharge and is completed, when all of the liquid sample and the marker component dissolved therein are discharged to the outside of the reaction tank 1.
