PROBLEM TO BE SOLVED: To improve accuracy of failure detection in a solid-state image pickup device and image pickup system that are capable of detecting a failure while picking up an image.SOLUTION: A solid-state image pickup device includes: a voltage supply unit for supplying predetermined voltage; and a plurality of sets, each of which comprises a first pixel, a second pixel, and a control signal line. The first pixel includes: a photoelectric conversion unit; a first node; a first transfer transistor connected to the photoelectric conversion unit and the first node; and a first reset transistor connected the first node. The second pixel includes: a second node; a second transfer transistor connected to the second node; and a second reset transistor connected the second node. The control signal line is connected in common to a gate of the first transfer transistor and a gate of the second transfer transistor. The solid-state image pickup device further comprises a switch for switching conduction and non-conduction of an electric path between the voltage supply unit and a second transfer transistor included in each of the plurality of sets.SELECTED DRAWING: Figure 1
