PROBLEM TO BE SOLVED: To provide a detection apparatus capable of simply and inexpensively determining authenticity of a genuine article and a forged article, and to provide an information determination system, a body to be detected, an identification body and an electronic device.SOLUTION: A detection apparatus 10 includes: a body 20 to be detected including an identification body 22 which is marked with an ink having respectively different reflective properties in no less than three different wavelengths, and an irreversible thermal discoloration section 24; a plurality of light-emitting sections 14a, 14b and 14c for emitting light to the identification body 22; and a light-receiving section 16 for receiving light reflected by the identification body 22, out of the light emitted from the light-emitting sections 14a, 14b and 14c. The plurality of light-emitting sections 14a, 14b and 14c respectively emit light of wavelengths corresponding to the selected reflective properties in the ink. The detection apparatus 10 includes a color recognition section 30 for recognizing a color of the thermal discoloration section 24. |
