A non-volatile semiconductor storage device has: a plurality of memory strings with a plurality of electrically rewritable memory cells connected in series; and a capacitor element area including capacitor elements. Each of the memory strings includes: a plurality of first conductive layers laminated on a substrate; and a plurality of first interlayer insulation layers formed between the plurality of first conductive layers. The capacitor element area includes: a plurality of second conductive layers laminated on a substrate and formed in the same layer as the first conductive layers; and a plurality of second interlayer insulation layers formed between the plurality of second conductive layers and formed in the same layer as the first interlayer insulation layers. A group of the adjacently-laminated second conductive layers is connected to a first potential, while another group thereof is connected to a second potential.
