PROBLEM TO BE SOLVED: To simplify the manufacture of a fluorescent sensor and reduce costs, to enlarge the range of solution to be analyzed by using a completely identical device, to improve the dynamical features of an analysis method utilizing the fluorescent sensor, and to achieve a technical product existing in an increase in analysis sensitivity using an X-ray fluorescent method. SOLUTION: The fluorescent sensor based on the multichannel structure has a microchannel, having an adsorbent microgranules arranged in the microchannel at one side of the end face of the multichannel structure. In the fluorescent sensor, the multichannel structure is one polycapillary tube for forming a microchannel by the entire capillary. The microchannel is filled with a two-layer immiscible substance, one of the two layers is formed by water or solution, the other layer is formed by an organic substance, and the adsorbent microgranules arranged in the microchannel is placed on a layer of water or solution.
