PROBLEM TO BE SOLVED: To provide a wearing article enabling measurement of spread of biological fluid at higher accuracy.SOLUTION: A wearing article 100A detects spread of biological fluid on the basis of impedance change between electrode groups ET. The electrode groups ET are formed on a surface of a piece of sheet of a plurality of sheets composing the wearing article 100A. The electrode groups ET comprise at least two electrodes 21 maintaining such a state as to be mutually insulated when the biological fluid is spread and also mutually connected via a conductive wire 22. A resistance value of the conductive wire 22 becomes lower than a resistance value of the electrode 21.SELECTED DRAWING: Figure 2
