A particle detecting device includes a frame, a chamber that is disposed within the frame, a sample injection flow path for injecting, into the chamber, a fluid that includes particles, from a first inlet opening that is provided in the frame, an adjusting mechanism that adjusts a state of the fluid within the chamber by supplying a fluid, from which the particles have been removed, into the chamber through an adjusting flow path that connects to the chamber from a second inlet opening that is separate from the first inlet opening that is provided in the frame, and a detecting mechanism that detects particles included within the fluid, by shining a light into the fluid within the chamber. |
