Abstract
Abstract An MIM type electric element has an upper electrode, a lower electrode, and a barrier layer held therebetween and composed of an insulator or a semiconductor. The lower electrode contains a noble metal crystal having a facet of a plate-shaped crystal formed on a substrate. The facet has a plane given by the crystal face (111) and contains a region having a plane orientation variance angle of not more than 1° by X-ray diffraction.
