This invention provides a turbidity measurement device wherein a measurement result can be obtained with high accuracy without being influenced by a flow of the sample or the outside light and with securing an improved optical transparency by cleaning a portion where the light to be measured passes at a time of measurement with a simple structure. The turbidity measurement device A comprises a body unit U1 comprising a sample introducing section U1a and an air tight section U1b, a cleaning unit U2 that is arranged in the sample introducing section U1a and that introduces a sample in and out of the sample introducing section U1a or confines the sample inside the sample introducing section U1a and that cleans a predetermined section of the sample introducing section U1a in association with a rotational movement around a center axis U1x of the elliptical shape in the body unit U1, a light source 3 that is arranged in the air tight section U1b and that irradiates the light on the liquid sample, and a light detecting section 4 that is arranged in the air tight section U1b and that detects the transmitted light LT and the scattered light LS irradiated from the light source 3.
