Abstract
A solid-state imaging device includes column amplifiers that are each provided for a different one of column signal lines. Each column amplifier includes: a constant current circuit that supplies a constant current; an amplifier circuit that is connected in series with the constant current circuit, and amplifies a pixel signal from a corresponding column signal line and outputs the amplified signal from a point of connection with the constant current circuit; and a resistor circuit that is connected in parallel with the amplifier circuit and has a constant resistance.
