According to one embodiment, a stack includes first and second wiring structures and an inspection circuit. The inspection circuit includes a switching circuit having an input terminal, a drive terminal, and an output terminal electrically connected with a discharge mechanism. The inspection circuit is configured such that, in a state where a first electric connection is made in the first wiring structure and a second electric connection is made in the second wiring structure, at the time of applying charges to first and second electrodes, the charge applied to the second electrode flows to the drive terminal through the second wiring structure to bring the input terminal and the output terminal of the switching circuit into an electrically conducted state, and the charge applied to the first electrode flows to the discharge mechanism through the first wiring structure and the switching circuit. |
