Abstract
First conductive layers extend in a first direction horizontal to a substrate as a longitudinal direction, and are stacked in a direction perpendicular to a substrate. An interlayer insulating layer is provided between the first conductive layers. The variable resistance layers functioning as a variable resistance element are formed continuously on the side surfaces of the first conductive layers and the interlayer insulating layer. A columnar conductive layer is provided on the side surfaces of the first conductive layers and the interlayer insulating layer via the variable resistance layers. First side surfaces of the first conductive layers are recessed from a second side surface of the interlayer insulating layer in the direction away from the columnar conductive layers.
