Photosensitive cells each includes a photodiode ( 1 ), a transfer gate ( 2 ), a floating diffusion layer portion ( 3 ), an amplifying transistor ( 4 ), and a reset transistor ( 5 ). Drains of the amplifying transistors ( 4 ) of the photosensitive cells are connected to a power supply line ( 10 ), and a pulsed power supply voltage (VddC) is applied to the power supply line ( 10 ). Here, a low-level potential (VddC_L) of the power supply voltage has a predetermined potential higher than zero potential. Specifically, by making the low-level potential (VddC_L) higher than channel potentials obtained when a low level is applied to the reset transistors ( 5 ), or channel potentials obtained when a low level is applied to the transfer gates ( 2 ), or channel potentials of the photodiodes ( 1 ), a reproduced image with low noise is read.
