To reduce influence of noise and to provide images of high image quality.

A solid-state imaging device 4 includes: a plurality of vertical signal lines 23 provided for each column of a plurality of pixels 21, for receiving signals from the pixels 21 of the corresponding column; and a plurality of signal processing parts 26 for respectively processing the signals of the plurality of vertical signal lines 23 on the basis of ramp signals Vramp and a reference voltage GND. To first wiring 61 connecting, in common, input parts of the ramp signals in the plurality of signal processing parts 26, the ramp signals Vramp are supplied on one side of a row direction. To second wiring 62 in common for input parts of the reference voltage GND in the plurality of vertical signal lines 23, the reference voltage GND is supplied on the one side of the row direction, and the reference voltage GND is not supplied on the other side of the row direction.
