PROBLEM TO BE SOLVED: To provide an information code which can be hardly read by a general reader, meanwhile, can be surely read when reading operation is performed by using a specific reader.SOLUTION: In a code area 20, a plurality of bright color modules exhibiting reflection characteristic of bright color and a plurality of dark color modules exhibiting reflection characteristic of dark color, when light of a second wavelength range is irradiated, are arranged. A coating part 11 is provided on a predetermined area within the code area 20. The coating part 11 permits transmission of reflection light from each module which constitutes the code area 20, but prohibits transmission of light of a first wavelength range when the light of the second wavelength range is irradiated. |
