摘要

The present invention provides a technique capable of easily and accurately performing identification and inspection of a three-dimensional structure. An information reading device of a three-dimensional structure 10 acquires information represented by a mark portion 12 in the three-dimensional structure. The irradiation unit 210 includes a light source 211 that emits near-infrared excitation light 31 that excites a near-infrared fluorescent dye, and irradiates near-infrared excitation light emitted from the light source toward the mark unit 12. The optical filter 220 blocks near-infrared fluorescent light emitted from a near-infrared fluorescent dye while blocking near-infrared excitation light. The light receiving unit 230 receives near-infrared fluorescence transmitted through the optical filter. The second control unit 240 controls the operation of the irradiation unit and the light receiving unit. And a 2nd control part acquires the information which the mark part 12 represents based on the data received by the light-receiving part. [Selection] Figure 3
