An image sensor , comprising: a) a plurality of pixels arranged in the form of a matrix having a plurality of pixel columns, each of the plurality of pixels comprising: - a photoelectric conversion unit that converts light to charge; - a transfer unit that transfers the charge converted by the photoelectric conversion unit ; - a floating diffusion to which the charge converted by the photoelectric conversion unit is transferred by the transfer unit ; - a reset unit that resets a potential of the floating diffusion to a reset potential; an amplification unit , connected to the floating diffusion , that outputs a first signal and a second signal; a first selection unit that outputs the first signal, and a second selection unit that outputs the second signal; b) a first signal line to which the first signal is outputted, the first signal being based upon the potential of the floating diffusion to which the charge has been transferred by the transfer unit from the photoelectric conversion unit ; c) a second signal line to which the second signal is outputted, the second signal being based upon the reset potential of the floating diffusion that is reset by the reset unit, the first signal line and the second signal line being separately provided for each of the pixel columns of the plurality of pixels; characterized by : an electrode or wiring for shielding provided between the first signal line and the second signal line , to which a constant potential is applied. a) a plurality of pixels arranged in the form of a matrix having a plurality of pixel columns, each of the plurality of pixels comprising: - a photoelectric conversion unit that converts light to charge; - a transfer unit that transfers the charge converted by the photoelectric conversion unit ; - a floating diffusion to which the charge converted by the photoelectric conversion unit is transferred by the transfer unit ; - a reset unit that resets a potential of the floating diffusion to a reset potential; an amplification unit , connected to the floating diffusion , that outputs a first signal and a second signal; a first selection unit that outputs the first signal, and a second selection unit that outputs the second signal; - a photoelectric conversion unit that converts light to charge; - a transfer unit that transfers the charge converted by the photoelectric conversion unit ; - a floating diffusion to which the charge converted by the photoelectric conversion unit is transferred by the transfer unit ; - a reset unit that resets a potential of the floating diffusion to a reset potential; an amplification unit , connected to the floating diffusion , that outputs a first signal and a second signal; a first selection unit that outputs the first signal, and a second selection unit that outputs the second signal; an amplification unit , connected to the floating diffusion , that outputs a first signal and a second signal; a first selection unit that outputs the first signal, and a second selection unit that outputs the second signal; b) a first signal line to which the first signal is outputted, the first signal being based upon the potential of the floating diffusion to which the charge has been transferred by the transfer unit from the photoelectric conversion unit ; c) a second signal line to which the second signal is outputted, the second signal being based upon the reset potential of the floating diffusion that is reset by the reset unit, the first signal line and the second signal line being separately provided for each of the pixel columns of the plurality of pixels; <EOS>
