    Abstract: An image sensor (A) includes a transparent cover (1) having a first face on an image reading region side and a second face on the opposite side to the first face, a light source (52) for irradiating the image reading region with light from above the second face, and a plurality of light receiving elements (53) for receiving a fraction of the light reflected from the image reading region to output an image signal according to the amount of light. The transparent cover (1) includes a transparent cover body (10) made of a synthetic resin, and a transparent glass member (20) corresponding to the image reading region. This transparent glass member (20) is exposed from the first face.
