Abstract: According to one embodiment, a semiconductor storage device is provided which includes a stacked body, a first pillar portion, a first separating portion, and a first supporting post. In the stacked body, a plurality of insulating layers and a plurality of electrically conductive layers are stacked alternately one on another. The stacked body is provided on a predetermined electrically conductive film. The first pillar portion includes a plurality of memory cells, and penetrates through the stacked body in a stacking direction of the stacked body. The first separating portion separates the stacked body into a plurality of blocks. The first supporting post extends locally within the stacked body from an upper surface of the predetermined electrically conductive film in the stacking direction.
