Zusammenfassung:	In order to obtain a small-sized and highly versatile image sensor and an image sensor device that are capable of obtaining reflected light information of both sides of an object to be read and transmitted light information from both sides of the object to be read and have a short conveying direction dimension while ensuring conveying quality, the image sensor and the image sensor device comprise: a lighting unit extending in a main scanning direction and illuminating the object-to-be-read with light; a rod lens array for focusing light from the object to be read; and a light receiving unit for converting the light focused by the rod lens array into an electric signal. The lighting unit illuminates a first illumination region of the object-to-be-read with normal light from the normal line direction of the object to be read and a second illumination region with a tilted light tilted by a predetermined angle from the normal line direction of the object to be read, said second illumination region being apart from the first illumination region in a sub-scanning direction.
