A solid-state imaging apparatus includes a plurality of photoelectric conversion devices, a charge transfer device for transferring a signal charge converted by the photoelectric conversion devices, a signal charge detection portion for converting a signal charge transferred by the charge transfer device into a signal voltage, a reset circuit for resetting a potential of the signal charge detection portion, and an amplification portion for amplifying the signal voltage. The amplification portion includes a two-stage source follower, each supplied with power supply voltages different from the power supply voltage to be supplied to the reset circuit. The second stage source follower includes drive transistor, and a current source that changes a current amount according to a fluctuation of the reset potential VRD.
