ABSTRACT:
An image sensor having a photodetecting element array including a plurality of blocks linearly arrayed in a first scan direction, each block compromising a plurality of photodetecting elements, a plurality of switching elements for transferring charges generated in the photodetecting elements, and a drive IC for outputting the charges in the form of image signals. The switching elements in a block and the switching elements in another block located adjacent to the former block are connected by signal lines, in order of linear proximity to each other. The signal lines connecting the switching elements in a block to the switching elements in blocks on both sides of the former block are disposed oppositely with respect to the first scan direction, and are disposed in such a way that the shortest signal line is located closest to the photodetecting element array, the next shortest signal line is located next closest to the photodetecting element array, and so on. Further, a first wire at a fixed potential is disposed between the signal lines adjacent to each other. A second wire at the fixed potential is disposed outside the signal line which is located farthest from the photodetecting element array. Furthermore, a dummy wire for generating a voltage waveform in synchronism with that on each of the signal lines, the polarity of both the voltage waveforms being the same, is disposed outside the second wire.
