To inexpensively achieve a simple and reliable polarimeter and an urine-inspecting device that can be maintained and controlled without using any consumables such as test paper.
Polarized light is transmitted through a sample 3 to be tested containing water, chloroform, or acetone that is a solvent for rotating the polarization direction of light due to light Faraday effect when a magnetic field is applied and fructose, cane sugar, glucose, or protein that is a dissolved substance being dissolved in the solvent, and the angle of rotation of the dissolved substance is measured based on the resultant change in the polarization direction of light. A magnetic field is applied to the sample 3 to be measured and the polarization direction of light through it is changed, and the angle of polarization of the dissolved substance is measured based on the size of the magnetic field when the amount of change in the polarization direction caused by the dissolved substance and the amount of change in the polarization direction being developed due to the application of the magnetic field are in a specific relationship.
