Claim 5:
6. The nonvolatile semiconductor memory device according to claim 1, further comprising:
a plurality of third wiring layers provided above the plurality of second wiring layers of the third direction, the plurality of third wiring layers extended in the first direction;
a plurality of third stacked structures each comprising a second memory cell disposed between the third wiring layer and the second wiring layer at a crossing portion between each of the plurality of third wiring layers and each of the plurality of second wiring layers;
a second conductive layer provided in the same layer as the plurality of second wiring layers, the second conductive layer disposed to be adjacent to the plurality of second wiring layers in the first direction; and
a fourth stacked structure disposed at a crossing portion between the third wiring layer and the second conductive layer, wherein
the second conductive layer is not connected to other than the third wiring layer.
