STRUCTURE, STRUCTURE-FORMING METHOD, AND STRUCTURE-FORMING DEVICE

摘要

Structural color generation in any region can be visually recognized when a structure is seen from any angle so that a decorative effect attributed to the structural color generation is improved. A structure 10 has a processed part 14 formed by the occurrence of photodisintegration attributed to the application of pulsed laser light. A fine periodic composition in which a plurality of processed parts 14 are arranged in the form of grid cross points is formed in one region 11 of the structure 10. A large number of regions 11 are arranged in the structure 10. Each of a plurality of ranges obtained by the division of a surface in which the regions 11 are arranged is a region-forming range 16. One or more regions 11 are arranged in one region-forming range 16. The arrangement directions of the processed parts 14 formed in each of a large number of regions 11 vary according to the region-forming ranges 16.
