摘要：
A measuring device includes a total internal reflection prism having a total reflection plane that an object to be measured contacts, a light source to emit light to make the light having a wavelength equal to or greater than 7 micrometers (μm) and equal to or less than 12 μm incident on the total reflection plane, and a sensor to detect light intensity of the light reflected by the total reflection plane. In the measuring device, an equation
