PURPOSE: To obtain a package at a low cost, by further providing a filter and patterns for light shielding and position aligning targets on a glass plate, on which an electrode pattern for attaching a solid image element is provided.
CONSTITUTION: On a glass plate 2, outer leads 3, a light shielding pattern 4 and a target pattern 5 are formed by Cr. A filter pattern 6 is formed from dyed gelatin by a photoengraving method. The patterns agree with the bonding pad of a pellet 7, a picture element shielding part, a target pattern 9 and a picture element receiving part, respectively. The pad 8 of the pellet is overlapped on the outer leads 3 of a substrate. The targets 5 and 9 are aligned and positioned in a fused solid 10. It is desirable that an interval between the filter 6 and the pellet 7 is 10 μm or less. A gap is filled with a transparent resin. Or the light receiving part is sealed in an airtight manner. In this constitution, the substrate having the same function of an expensive ceramic package can be obtained by simple processes at a low cost without using an expensive ceramic package.
