According to one embodiment, a nonvolatile semiconductor memory device includes a substrate, an electrode layer provided above the substrate, a first insulating layer provided on the electrode layer, a stacked body provided on the insulating layer, a memory film, a channel body layer, a channel body connecting portion and a second insulating layer. The stacked body has a plurality of conductive layers and a plurality of insulating film alternately stacked on each other. The memory film is provided on a sidewall of each of a pair of holes penetrating the stacked body in a direction of stacking the stacked body. The channel body layer is provided on an inner side of the memory film in each of the pair of the holes.
