A spectroscopic measurement apparatus includes a light emitter simultaneously emitting light including light having all wavelengths in a wavelength range from 400 nm to 700 nm to a measurement target, a light disperser dispersing a reflected light reflected by the measurement target to a predetermined wavelength, a light receiver that receives the light dispersed by the light disperser and outputs a second light reception amount indicating a light intensity of the received light, and a calculator that receives the second light reception amount of each wavelength and calculates a reflection spectrum when the measurement target is irradiated with light, in which the calculator calculates reflectance of a predetermined wavelength using the second light reception amounts of a plurality of wavelengths.
