Abstract
A low-priced contact type color image sensor formed without the need to provide color filters on a linear image sensor. The color filters are formed on a surface of a document side of a transparent protective glass in direct contact with a document for flattening the light irradiation surface, such that the pitch thereof is equal to that of light receiving elements of a linear image sensor.
