A solid-state imaging device includes: a plurality of pixels each converting the amount of incident light into an electric signal and disposed in a plurality of columns to be deviated from the neighboring pixels in a row direction or in a column direction; a plurality of analog-to-digital converting units each converting an analog signal obtained from a corresponding pixel into a digital signal and disposed along a column in parallel; a plurality of column signal lines outputting the analog signals of the pixels of each of the plurality of pixel columns, disposed along the pixel columns, and making pairs; and a plurality of switching circuit units each selecting one column signal line of a corresponding pair of column signal lines. In the solid-state imaging device, the analog-to-digital converting units are connected to the output sides of the switching circuit units.
