PROBLEM TO BE SOLVED: To provide an absorbance measuring instrument for a microplate, capable of carrying out measurement as to at least two wavelengths. SOLUTION: This absorbance measuring instrument 1 has an irradiation part 10 for emitting at least two lights modulated by respective different modulation frequencies and having wavelengths different from each other, to a well 6 of the microplate 5, along a substantially same optical axis, a photoreception part 20 for receiving the light emitted from the irradiation part 10 and transmitted through the well 6, and for outputting a detection signal in response to an intensity of the light, and a discrimination part 30 for discriminating the detection signals as signals corresponding respectively to at least the two lights, using a difference in the modulation frequencies.
