• any one or more of a size, a height, a planar shape, an arrangement interval, and an arrangement direction of the first protrusions in the first print region is/are different from a corresponding one or more of a size, a height, a planar shape, an arrangement interval, and an arrangement direction of the second protrusions in the second print region;
• and
• when an extracted area that is about 3 cm by about 3 cm is extracted from any location in the print layer, the first and second print regions are in the extracted area, and at least either a number of first print regions or a number of second print regions in the extracted area is more than one.
