Abstract
A particulate concentration detector including a detection mechanism having a light emission unit and light reception unit. The particulate concentration detector detects the concentration of particulates suspended in a liquid from the light amount detected by the detection mechanism. The detection mechanism includes a first light guide, a second light guide, a liquid chamber, and a third light guide. The first light guide is arranged at a location facing toward a light emission surface of the light emission unit. The second light guide is arranged at a location facing toward a light reception surface of the light reception unit. The liquid chamber is formed between the first light guide and second light guide and allows the liquid to flow therein. The third light guide is arranged in an oscillatable manner in the liquid chamber so as to face toward the first light guide and the second light guide.
