Abstract
An electro-resistance element that has a different configuration from conventional elements and shows outstanding resistance change characteristics is provided. An electro-resistance element has two or more states in which electric resistance values are different, and is switchable from one of the two or more states into another by application of a predetermined voltage or current. The electro-resistance element includes: a multilayer structure including an upper electrode, a lower electrode, and an electro-resistance layer sandwiched by the electrodes, the multilayer structure disposed on a substrate; wherein the electro-resistance layer has a spinel structure, and a surface of the lower electrode that faces the electro-resistance layer is oxidized. The electro-resistance element can be manufactured by a manufacturing process at 400° C. or lower.
