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

摘要

The present invention enables the structure color of any region to be seen when looking at a structure from a desired angle, and improves a decorative effect achieved by the structure color being presented. A structure (10) having a processed part (14) formed by the onset of photodisintegration due to irradiation from pulsed laser radiation, wherein a fine periodic structure is formed in one region (11) of the structure (10), the structure having a plurality of the processed parts (14) arranged on points of a grid. A plurality of regions (11) are arranged on the structure (10), and each of a plurality of ranges created when a surface in which the regions (11) are arranged is divided is designated as a region-forming range (16); and one or a plurality of regions (11) are arranged on one region-forming range (16). The plurality of processed parts (14) formed in each of the multiple regions (11) are arrayed in different directions for each of the region-forming ranges (16).
