PROBLEM TO BE SOLVED: To provide an integration circuit and a photodetection device achieving reduction in power consumption and increase in speed.SOLUTION: The photodetection device 1 includes a photodiode PD and an integration circuit 10. The integration circuit 10 includes an amplifier circuit 20, a capacitor element C, a first switch SW, and a second switch SW. The second switch SWis connected between a reference potential input terminal to which reference potential Vref is input and a terminal of the capacitor element C on the inverting input terminal side of the amplifier circuit 20, and performs opening/closing operation according to a level of a second reset signal Reset2 to apply the reference potential Vref to the terminal of the capacitor element C. |
