Abstract

The present invention relates to an oil mist detecting device (1) that can reduce the intensity of undesired reflected light to prevent the deterioration of detection accuracy. The oil mist detecting device (1) is one that includes a container (6, 6a, 6b) having: a containing space (7, 7a, 7b) containing a light emitting element (4) and a light receiving element (5); and an introduction space (8) into which oil mist is introduced, and detects the oil mist by in the container (6, 6a, 6b), irradiating the oil mist with light emitted from the light emitting element (4) and receiving light reflected or scattered by the oil mist by the light receiving element (5). In addition, the oil mist detecting device (1) includes a lens (9, 15, 16) that separates between the containing space (7, 7a, 7b) and the introduction space (8) and is formed with a bottom-equipped groove (18) opened on a containing space side. Further, the lens (9, 15, 16) has a first light guiding region (19a) adapted to guide the light emitted from the light emitting element (4) to the introduction space (8) as one part resulting from division by the bottom-equipped groove (18), as well as, as the other part resulting from the division by the bottom-equipped groove (18), having a second light guiding region (19b) adapted to guide the light reflected or scattered by the oil mist to the light receiving element (5).
