A non-volatile semiconductor storage device includes a plurality of memory element groups, each of the memory element groups having a plurality of memory elements, each of the memory elements having a resistance-change element and a Schottky diode connected in series. Each of the memory element groups includes: a first columnar layer extending in a lamination direction; a first insulation layer formed on a side surface of the first columnar layer and functioning as the resistance-change element; and a first conductive layer formed to surround the first columnar layer via the first insulation layer. The first conductive layer is formed of metal. The first columnar layer is formed of a semiconductor having such a impurity concentration that the first conductive layer and the semiconductor configure the Schottky diode.
