Abstract: The present invention relates to a chemically strengthened glass having a first principal surface and a second principal surface facing the first principal surface, at least a portion of the first principal surface being chemically strengthened, wherein the depth of a compressive stress layer in at least a portion of the first principal surface continuously changes. This chemically strengthened glass can be suitably used in an application in which chemical strengthening characteristics that differ among different regions in the same plane are desired in a chemically strengthened glass.
