The present invention provides a solid-state image sensor comprising a source follower amplifier on a single chip capable of preventing a gain loss caused by a back gate effect. In the solid-state image sensor including multi-stage single-chip source follower amplifier, one stage of the multi-stage source follower amplifier has a load transistor 5 whose source and gate are connected to an output signal 3 via a capacitor 7, and a DC voltage 6 is applied via a resistor 8 having a high resistance.
