A measurement device for measuring the state of an object to be measured by absorption spectroscopy includes an irradiator that irradiates the object to be measured with irradiation light, a retroreflective first prism disposed on an opposite side from the irradiator with respect to the object to be measured, a retroreflective second prism disposed on the same side as the irradiator with respect to the object to be measured, a light receiver that receives the irradiation light that has passed through the object to be measured multiple times between the first and second prisms, and a first light guide disposed on the same side as the first prism and configured to guide the irradiation light towards the light receiver. The first and second prisms are not concentric in a first direction, and a plurality of passages for the irradiation light is arranged in two rows along the first direction on an optical surface of each of the first and second prisms.
