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 the both sides of the object-to-be-read and have a short length in conveying direction while ensuring conveying quality, the image sensor and the image sensor device include: a lighting portion extending in a main scanning direction and emitting light to the object-to-be-read; a rod lens array for imaging light from the object-to-be-read; and a light receiving portion for converting the light imaged by the rod lens array to an electric signal. The lighting portion emits a normally directed light from the normal direction of the object-to-be-read to irradiate a first irradiation region of the object-to-be-read, and an inclined light inclined by a predetermined angle from the normal direction of the object-to-be-read to irradiate a second irradiation region being apart from the first irradiation region in a sub-scanning direction.
