Abstract
A particulate measurement device includes: a nozzle which discharges liquid from an opening to form a flow of the liquid; a light emitter which emits light such that the light propagates in a region where the flow of the liquid is formed; a photodetector provided outside the region to receive the light from a partial region extending along a longitudinal direction of the region; and an air flow forming unit which forms a flow of gas along a direction in which the liquid flows, on an outer periphery of the region.
