Abstract
Provided is a top plate for a cooking device including a glass sheet () and a light-shielding film () formed on a lower surface () of the glass sheet () through sputtering. The light-shielding film () contains an oxide, a nitride, or an oxynitride of a transition metal of Group 6 to Group 11 on the periodic table. In this manner, a color close to grey can be achieved as a color of the light-shielding film () while insulating properties of the light-shielding film () are secured.
