A cover glass for use in a mobile device such as a touch-panel mobile telephone has a thickness in the range of, for example, 0.3mm to 1.5mm. A recess that can be recognized as a character or a figure when watching from the front side of the mobile device or a recess that can be recognized when touching from the front side of the mobile device is formed on at least one of opposite main surfaces of the cover glass. A surface of this recess is an etched surface treated by etching. |
