The invention discloses a capacitance detection device used for fingerprint identification, comprising a detection screen, a conductor frame and a detection device. The detection screen comprises a plurality of detection units, and each detection unit comprises a first conductor layer, a second conductor layer, a third conductor layer, and a fourth conductor layer. The induction capacitance can be generated by the first conductor layer and a finger touching the detection screen. The feedback capacitance can be generated between the first conductor layer and the second conductor layer, and the integral capacitance can be generated between the third conductor layer and the fourth conductor layer. When the finger contacts the detection screen, the finger is electrically connected with the conductor frame. The detection device is used to charge the induction capacitance and the feedback capacitance in the sampling phase, and can be used to measure and control the transfer of the charges of the induction capacitance and the feedback capacitance to the integral capacitance in the integral phase, and at the same time, can be used to measure the voltage variable quantity of the integral capacitance in the integral phase, and can be used to calculate the induction capacitance according to the voltage variable quantity. The capacitance detection device is advantageous in that the fingerprint detection accuracy can be improved, and at the same time, the circuit noises can be effectively reduced, and the power consumption and the area of the circuit can be reduced. The invention also discloses a fingerprint identification device.
