According to one embodiment, a nonvolatile memory device comprises a plurality of first lines, a plurality of second lines, and memory cells. Each of the memory cells comprise a variable resistor, and a diode. The variable resistor includes a first metal oxide film and is configured to reversibly change resistance value by energy application. The diode includes a second metal oxide film and is connected in series to the variable resistor. The first metal oxide film has at least one of dielectric constant lower than that of the second metal oxide film and physical film thickness greater than that of the second metal oxide film.
