(57) [Summary] [PROBLEMS] To provide a device which has a simple structure and a simple method of use, and which rapidly measures an analyte by utilizing a specific reaction such as an antigen-antibody reaction. An immunoassay device having a filter, a labeling reagent-containing member, and a porous carrier having one or a plurality of reaction regions, wherein the porous carrier has the filter and the labeling reagent-containing member at its upstream end. Sandwiched between and The reaction region is located downstream of and away from the filter and the labeling reagent-containing member, the labeling reagent-containing member contains a labeled reagent, and the capture reagent is immobilized in the reaction region. A measuring device for measuring an analysis target by using a specific reaction. |
