PROBLEM TO BE SOLVED: To also measure the absorbance of a sample in a sensor utilizing total reflection attenuation. SOLUTION: The sensor utilizing total reflection attenuation comprises a dielectric block 10, a light source 14 for generating light beams 13, an optical system 15 for allowing the light beams 13 to enter an interface 10b so that various incident angles can be obtained, and a light detection means 17 for detecting the light beams 13 that are totally reflected from interface 10b for making parallel. The sensor further has a light source 50 for generating light beams 56 for measuring thermal lens effect, an optical system 51 for allowing the light beams 565 to enter the dielectric block 10, a mask 52 for shielding one portion of the light beams 56 through the dielectric block 10, and a light detection section 54 for detecting the light beams 56 through the dielectric block 10 via a mask 52 and an optical system 53, thus measuring thermal lens effect that depends on the absorbance of a sample 11.
