A contact area-sensor includes a plurality of image scanners, each of which includes an image scanning sensor substrate in which a plurality of sensor sections are aligned in a matrix manner so as to scan an image; and a connecting line having flexibility, for connecting the plurality of image scanners to each other. On this account, it is possible to provide a small, thin, light-weighted contact area-sensor, which is capable of obtaining a wide area of an image, while ensuring superior portability.
