Abstract
A directly detectable image sensor applicable to an image reader of a facsimile and others includes two glass substrate members which are bonded to each other, and an array of miniature lenses arranged at the interface between the two substrate members and each having a different refractive index from the substrate members. Sensor elements and electrodes are provided on one major surface of a sensor substrate which is made up of the two glass substrate members, a document being laid closely on the other major surface of the sensor substrate. Light is propagated through the sensor substrate from the sensor elements and electrodes side to reach the document, while a reflection from the document is focused onto the sensor elements by the miniature lenses.
