There is provided an image sensor which can reduce loss in light emitted from a light emitting section toward an object to be sensed and also variability in the distribution of light and which can be produced with a small-sized structure with a reduced number of parts and with a decreased manufacturing cost. An optical path from the light emitting section to a transparent covering on which the object is to be placed is surrounded by a light reflecting portion. Light from the light emitting section can be irradiated onto the transparent covering without reduction in the amount of light while being repeatedly reflected by the light reflecting portion. The light reflected by the object is condensed by a condensing lens, the condensed light being then received by a light receiving section mounted on the same base plate as in the light emitting section. At the light receiving section, the light is converted into an electrical signal.
An image sensor for irradiating light to an object to be sensed and for converting the reflected light from said object into an electrical signal representative of an image on said object, said image sensor comprising:
