Abstract
According to one embodiment, the recess has a side surface and a bottom surface. The side surface is continuous with the major surface. The bottom surface is positioned lower than the major surface. The stacked body is provided above the major surface of the substrate. The stacked body includes a plurality of electrode layers stacked with an insulating body interposed. The columnar portion includes a semiconductor body and a stacked film. The semiconductor body extends in a stacking direction of the stacked body through the stacked body. The semiconductor body contacts the side surface and the bottom surface of the recess of the substrate. The stacked film includes a charge storage portion and is provided between the semiconductor body and the stacked body higher than the major surface of the substrate. The stacked film is not provided in the recess of the substrate.
