<P>PROBLEM TO BE SOLVED: To provide a technology capable of reducing back ground noise or cross talk noise, and carrying out the optical observation of a large number of fine particles with high sensitivity and high accuracy. <P>SOLUTION: A particle fixing structure 14 has a plurality of holding holes 9 respectively holding inspected particles for detecting light emitted from substances indicating the existence of ingredients constituting the inspected particles; and comprises a platy translucent base plate 15, a holding portion 20 disposed on a first surface of the base plate 15 and formed with a plurality of the holding holes 9, and a light shielding film 19 disposed on a second surface of the base plate 15. The holding holes 9 open on an upper surface of the holding portion 20, and extend to the first surface of the base plate 15. The light shielding film 19 has a plurality of opening portions 9 exposing the second surface of the base plate 15 at positions corresponding to the plurality of the holding holes 9. <P>COPYRIGHT: (C)2012,JPO&INPIT |
