Abstract
An object of the present invention is to prevent a sensitivity difference between pixels. There are disposed plural unit cells each including plural photodiodes 101A and 101B, plural transfer MOSFETs 102A and 102B arranged corresponding to the plural photodiodes, respectively, and a common MOSFET 104 which amplifies and outputs signals read from the plural photodiodes. Each pair within the unit cell, composed of the photodiode and the transfer MOSFET provided corresponding to the photodiode, has translational symmetry with respect to one another. Within the unit cell, there are included a reset MOSFET and selecting MOSFET.
