The field effect transistor outputs an electric signal corresponding to change in dielectric constant between the electrodes, the change being caused by incident light on the photoelectric conversion layer. Cpd1, Cn1, Cpd2 and Cn2 satisfy a relation of Cpd1/Cn1<Cpd2/Cn2 where a capacitance value of a first photoelectric converter in a state of receiving no incident light is Cpd1, a capacitance value between a first node and a first channel region is Cn1, a capacitance value of a second photoelectric converter in a state of receiving no incident light is Cpd2, and a capacitance value between a second node and a second channel region is Cn2.
