<P>PROBLEM TO BE SOLVED: To improve resolution with a simple and easy constitution in the non-invasive analysis of fluid. <P>SOLUTION: A fluid detection sensor 1, which is attachably and detachably provided on the outside of a translucent tube 13 through which a fluid object is circulated, includes: light-emitting elements 18a to 18f which emit light having a single peak wavelength; a light receiving element 19 which is disposed at a place across the tube 13 separated at a fixed distance from a light emission end 111a from which the light of the light-emitting elements 18a to 18f is emitted, and has a plurality of light receiving surfaces 123a independent from each other; and a prism 17 disposed between the tube 13 and the light receiving element 19 or between the light emission end 111a and the tube 13. The light receiving element 19 has different light receiving surfaces 123a which receive the light dispersed by the prism 17, respectively. <P>COPYRIGHT: (C)2012,JPO&INPIT |
