A method for detecting or assaying one constituting member in a specific binding pair, for example, the antigen in an antigen/antibody pair, by utilizing specific binding such as binding between an antigen and an antibody, together with redox reaction for detecting a label, wherein an oxygen micro-electrode with a sensing surface area of 1 mm2 or less is used; and an apparatus to which the method is applicable. According to the method and by using the apparatus, redox reaction for assaying the label can be completed in such a short time as several minutes. Therefore, an inexpensive disposable apparatus for household use can be realized.
