The present invention has an object of providing a method for driving a solid-state imaging device which includes photodiodes 210 arranged in columns and rows and vertical CCDs 220 each of which is provided for a corresponding one of the columns of the photodiodes and includes transfer electrodes V1 to V6, the method for driving the solid-state imaging device making it possible to reduce aged deterioration of a vertical CCD and a reading voltage and including: reading a signal charge from each of the photodiodes 210 by setting an electric potential of one of the transfer electrodes to a high-level electric potential VH; and transferring, in a column direction, the read signal charge by applying, to each of the transfer electrodes V1 to V6, a driving pulse having a mid-level electric potential VM and a low-level electric potential VL, the mid-level electric potential VM being lower than the electric potential VH, and the low-level electric potential VL being lower than the electric potential VM, wherein, in the reading, while the electric potential VH is being applied, an electric potential of a transfer electrode that is adjacent to the transfer electrode having the electric potential VH is set to the electric potential VM, and an electric potential of a transfer electrode that is not adjacent to the transfer electrode having the electric potential VH is changed.
