The present invention provides a measurement device that is compact and portable, easy to operate, and capable of determining the quantity of an object of inspection with high sensitivity and accuracy. A measurement device according to the present invention is provided with an SPR sensor cell, a light source, and a light reception element. The SPR sensor cell has a plurality of optical waveguides. At least one of the plurality of optical waveguides constitutes a detection unit together with a metal layer on which a recognition substance for the object of inspection is fixed, and at least one of the other optical waveguides constitutes a reference unit together with a metal layer that does not include the recognition substance. 本发明提供种测量装置，其紧凑、便携、操作简便并且能够以高灵敏度和高精度确定被检查物的量。根据本发明的测量装置设置有SPR传感器元件、光源和光接收元件。SPR传感器元件具有多个光波导。多个光波导中的至少个光波导与固定有用于被检查物的识别物质的金属层起构成检测单元，所述多个光波导中的至少另个光波导与不含识别物质的金属层起构成参照单元。
