PROBLEM TO BE SOLVED: To hold the uniform intensity of light within a visualizing space without irregularity and to certainly visualize fine particles even if a cutoff substance is present in the visualizing space. SOLUTION: This visualizing apparatus is constituted of a laser beam oscillator 2, the visualizing space 4 substantially surrounded by a plurality of fixed reflecting mirrors 3 arranged in a peripheral direction and a polygon mirror 6 for allowing a laser beam, which is projected from the laser beam oscillator 2, to be incident into the visualizing space 4. The laser beam is allowed to be incident into the visualizing space 4 by operating the polygon mirror 6 while continuously changing an incident angle and the multiple reflection of the laser beam allowed to be incident into the visualizing space 4 is repeated in the visualizing space 4 by a plurality of fixed reflecting mirrors 3 to visualize fine particles present in the visualizing space 4.
