PURPOSE:To inexpensively obtain cover glass excellent in scratch resistance by bonding a sapphire plate excellent in scratch resistance to the surface of a glass plate good in processability. CONSTITUTION:A sapphire plate 2 with a thickness of 50-1000mum is bonded to the surface of a glass plate 1 by an adhesive 3 and both plates 1, 2 are chamfered to form chamfered parts 1a, 2a to be attached to a timepiece case so that the sapphire plate 2 is positioned on the surface side of the case. The glass plate 2 is composed of inorg. or org. glass and formed, for example, by applying chemical reinforcing treatment to inorg. glass with a thickness of 0.7mm of which both surfaces are ground. The sapphire plate 2 is formed by grinding both surfaces of a sapphire plate with a thickness of 500mum produced by a drawing-up method so as to obtain a thickness of 300mum.; The adhesive 3 to be used is composed of a liquid or sheet like epoxy adhesive and the thickness thereof is pref. 50mum or less. The glass plate 1 with a thickness of 0.7mm and the sapphire plate 2 with a thickness of 0.3mm are bonded so as to have a shape larger than a final shape and the bonded one is subjected to edge processing and chamfering to form cover glass with a thickess of 1mm.
