Photoelectric conversion apparatus with level photoreceiving surface

A photoelectric conversion apparatus constituted by a plurality of semiconductor element substrates arranged and fixed onto a base with an adhesive,

• wherein levels of opposite surfaces of said plurality of substrates to said base are adjusted in accordance with a thickness of said adhesive, with which said substrates are bonded, such that the opposite surfaces are set within the same plane;
• wherein said substrates are fixed by using not less than two types of adhesives having different properties;
• and
• wherein said adhesives include a first adhesive having elasticity and a second adhesive having elasticity lower than that of said first adhesive or having substantially no elasticity.

A photoelectric conversion apparatus having a two-dimensional photoreceiving surface comprising:

• a semiconductor element substrate provided with a plurality of photoelectric conversion elements arranged two-dimensionally;
• a base on which a plurality of said semiconductor element substrates are arranged and fixed;
• and
• an adhesive having an elasticity for fixing said plurality of semiconductor element substrates to said base, wherein said adhesive extends more widely at the adjacent portions of adjacent semiconductor substrates.

A photoelectric conversion apparatus constituted by a plurality of substrates, each of which has photoelectric conversion elements, and which are bonded to a base to be adjacent to each other;

• wherein said substrates are bonded to said base with an adhesive having elasticity;
• wherein said adhesive having elasticity is applied in regions other than adjacent portions of adjacent substrates;
• and
• wherein the adjacent portions have a second adhesive having no elasticity or elasticity lower than that of said adhesive having elasticity.
