PROBLEM TO BE SOLVED: To provide a measuring device capable of measuring each optical rotation of many wavelengths with a simple constitution. SOLUTION: This device includes the first polarizer 18 for transmitting a prescribed polarization component of light; a polarized-light modulation part 20 for modulating transmitted light into optional polarized light; the second polarizer 32 for allowing transmission of a prescribed polarization component of light transmitted through a measuring object 30 through the polarized-light modulation part 20; a dichroic mirror 80 for allowing transmission of a prescribed wavelength component of the transmitted light, and reflecting a wavelength component other than the prescribed wavelength component; the first filter 82 for allowing transmission of the first wavelength of light transmitted through the dichroic mirror 80; the second filter 84 for allowing transmission of the second wavelength of light reflected by the dichroic mirror 80; the first detection part 34 for detecting light intensity of light transmitted through the first filter 82; and the second detection part 36 for detecting light intensity of light transmitted through the second filter 84.
