PROBLEM TO BE SOLVED: To provide a color measuring instrument and a light source device, both reduced in size. SOLUTION: A plurality of white color LEDs 21, 22, 23, and color filters 24, 25, 26 respectively emit lights different in wavelengths; an irradiating light guide member 203 guides to a testing paper face a mixed beam mixed with the lights emitted from the plurality of white color LEDs 21, 22, 23, and color filters 24, 25, 26; a photoelectric transfer part 27 receives a reflected beam reflected by the test paper face, and converts the received reflected beam into a light intensity signal; and a color measuring part 3 resolves the light intensity signal converted by the photoelectric transfer part 27 in every of the plurality of wavelengths of the light source, and measures a color of test paper, on the basis of resolved light intensity signals.
