There is known a charge-distributing type range image sensor (for example, see Patent Literature 1). The range image sensor disclosed in Patent Literature 1 is a charge-distributing type range image sensor, and includes a plurality of range sensors. Each of the range sensors includes a charge-generating region generating charges in accordance with incident light, two signal charge-accumulating regions disposed to sandwich the charge-generating region in a one-dimensional direction and away from the charge-generating region, and two transfer electrodes disposed between the signal charge-accumulating region and the charge-generating region. A charge-distributing type range image sensor can be applied to Time-Of-Flight (TOF) type ranging.
