According to an embodiment, a semiconductor memory device includes a substrate, a stacked body, a plurality of first members, and at least one first insulating member. The stacked body is provided on the substrate and includes a plurality of electrode layers. The electrode layers are stacked apart from each other in a first direction and extend in a second direction parallel to an upper surface of the substrate. The first members are provided in the stacked body and extend in the first direction and the second direction. The first insulating member is provided in the stacked body and extends in the first direction and a third direction so that the electrode layers are divided into a plurality of regions in the second direction, the third direction intersecting with the second direction and being parallel to the upper surface of the substrate.
