The solid-state imaging device having pixels that are arranged in rows and columns and convert optical signals to electric signals to output the electric signals as voltage signals includes column signal lines each provided for a corresponding one of the columns and transmitting, in the direction of the columns, voltage signals outputted from the pixels, current sources each provided for and connected to a corresponding one of the column signal lines, column amplification circuits each provided for a corresponding one of the column signal lines and amplifying the voltage signals transmitted through the column signal lines, a current-source ground potential supply line supplying the current sources with ground potential, and a column amplification circuit ground potential supply line supplying the column amplification circuits with ground potential. The current-source ground potential supply line and the column amplification circuit ground potential supply line are interconnected at positions corresponding to the columns.
