Claim 12:
13. A nonvolatile semiconductor memory device comprising:
a first memory cell array provided with a plurality of first wiring layers extended to a first direction and arranged in a second direction crossing the first direction, a plurality of second wiring layers extended to the second direction and arranged in the first direction, and a plurality of first stacked structures including a first memory cell provided between the first wiring layer and the second wiring layer;
a plurality of first conductive layers provided in the same layer as the first wiring layer in a third direction crossing the first direction and the second direction and disposed to be adjacent to the first wiring layer in the second direction;
a plurality of second stacked structures including the plurality of the first conductive layers and the second wiring layers; and
an insulation layer provided between the plurality of first stacked structures and between the plurality of second stacked structures, wherein
the second stacked structure has a Young's modulus larger than a Young's modulus of the insulation layer.
