Photoelectric conversion device and information processing apparatus with resin covering the side of the photosensor substrate

An information processing apparatus comprising:

• a photoelectric conversion device comprising a photosensor substrate having plural photoelectric conversion elements on a light transparent substrate;
• and
• a mounting plate having a resin covering a side of said photosensor substrate, wherein there is a region where the surface of said mounting plate and at least a part of the surface of said photosensor substrate are substantially continuous, and said mounting plate has a convex or concave section to be used as a reference in mounting on an another member;
• a base plate for holding said photoelectric conversion device for the image reading;
• a light source for illuminating an image holding member;
• a conveying unit for conveying said image holding member;
• and
• a controller for controlling at least one of said photoelectric conversion device for the image reading, said light source and said conveying unit,
• wherein said photoelectric conversion device for the image reading is mounted on said base plate based on the mounting reference.
