PROBLEM TO BE SOLVED: To provide an optical measuring device capable of analyzing a trace substance with high sensitivity by efficiently applying excitation light from a light source to a sample and efficiently guiding light emitted from the sample to a photodetector. SOLUTION: In the optical measuring device A, an optical path is composed by a bundle of optical fibers 4, where optical fibers 4a-4c for excitation light for guiding light emitted from light sources 1a-1c to the sample for illumination and an optical fiber 4d for radiation light for guiding radiation light emitted from the excited sample to the photodetector 8 are bundled by surrounding one optical fiber 4d for radiation light positioned at the center by the plurality of optical fibers 1a-1c for excitation light.
