PROBLEM TO BE SOLVED: To provide an individual identifying method for a resin structure, which has high reliability for identification and a low cost for identification. SOLUTION: In this individual identifying method, an orientation pattern based on flow orientation property of a resin structure 11 is read out by an image pick up part 18, and an image datum to use for identification is obtained from the read out data through an A/D conversion part 19 and a feature extraction part 20. On the other hand, another image datum registered in advance in a memory part 27 of a registration control device 25 is read out through a readout part 28, and these data are compared in a comparison part 29. When the image data coincide with each other by this comparison, the resin structure 11 is identified as the resin structure read out in advance. |
