Abstract
An inference method includes inferring a value that includes a stress value in a region located 50 μm or shallower from a surface of a chemically strengthened glass, by receiving as input at least a temperature and a time used upon chemical strengthening, and stress values at three or more different depth positions 20 μm or deeper from the surface of the chemically strengthened glass that has been obtained by chemically strengthening a glass having a thickness of 0.2 mm or greater with the temperature and the time.
