Abstract text

A measuring apparatus 1a includes: light emitting elements 21 and 31, illuminating measurement light on an immunochromatographic test strip 41; a photodetecting element 22, detecting reflected light from the immunochromatographic test strip 41 due to illumination of the measurement light on a first position (band-like region 41c) on the immunochromatographic test strip 41; a photodetecting element 32, detecting reflected light from the immunochromatographic test strip 41 due to illumination of the measurement light on a second position (band-like region 41d) at a downstream side of the first position; and a controller 13, acquiring, based on output signals from the photodetecting elements 22 and 32, a time from a change of absorbance at the first position (band-like region 41c) to a change of absorbance at the second position (band-like region 41d).
