Abstract
According to an embodiment, a semiconductor memory device includes a substrate, an insulating film, a plurality of conductive films, an insulating member, a plurality of stacked bodies, and a first member. The insulating member is provided on the insulating film, is positioned between the conductive films in a first direction along the substrate, and extends in a second direction along the substrate, the second direction crossing the first direction. The first member is provided on the insulating member, is positioned between the stacked bodies in the first direction, and extends in a stacking direction of the plurality of electrode films of the stacked bodies. A width in the first direction of the insulating member is larger than a width in the first direction of the first member.
