A solid-state imaging device according to the present invention includes: a pixel portion including a plurality of unit pixels arranged in a matrix; a column signal line provided per column in the pixel portion; an AD conversion unit which converts a voltage of a pixel signal into a digital value by performing counting until a reference signal reaches the voltage of the pixel signal from the column signal line; and a clock signal generating unit which generates, to the AD conversion unit, a counter clock for the counting, and the clock signal generating unit switches, during a period of the AD conversion, a frequency of the counter clock from a first frequency to a second frequency that is different from the first frequency.
