<p>PURPOSE:To prevent a malfunction based on unnecessary light and to prevent oxygen from entering the surface of a solid-state image sensing element by performing printing with ink on a transparent substrate and baking the ink, thereafter by providing a light filter layer and then by forming a sealer layer. CONSTITUTION:First, a light absorption layer 18 is printed on a glass substrate 12 with silk screen ink mainly composed of glass. Then, AR coat is applied to both faces of the glass substrate 12 so that a light filter layer 14 is formed. Further, silk screen printing is performed on the outermost periphery of the glass substrate 12 other than the light filter layer 14 so that a sealer layer is printed. After printing, the sealer layer 16 is formed by baking so that a shading cap glass 10 is manufactured. Thus, it is possible to obtain the shading cap glass, which can prevent a malfunction based on unnecessary light and can be tightly bonded to the surface of a solid-state image sensing element to surely prevent oxygen from entering and further can stably maintain properties of the light absorption layer at the time of heat bonding.</p> |
