An optical measuring device (1) includes a measuring unit (an optical head (2) and a control unit (3)) that irradiates a detection portion (16) of an immunochromatographic test piece (K) with measurement light and measures light obtained from the detection portion (16) due to the irradiation with the measurement light, and a determination unit (4) that performs a determination regarding the immunochromatographic test piece (K) on the basis of a determination according to a comparison of a measurement value obtained by the measuring unit with a preset threshold value, the measuring unit performs the measurement of the light obtained from the detection portion (16) a plurality of times, and the determination unit (4) performs a determination regarding the immunochromatographic test piece (K) when the determination unit determines that a measurement value in an nth measurement is equal to or greater than the threshold value and also determines that a measurement value in an (n + 1)th measurement is equal to or g
