Abstract
A switching element is of a configuration that includes: an ion conduction layer () for conducting metal ions, a first electrode () and a second electrode () provided in contact with the ion conduction layer, a third electrode () that can supply metal ions to the ion conduction layer, and a diffusion prevention layer () provided between the ion conduction layer () and the third electrode () for preventing the diffusion of metal ions from the third electrode () to the ion conduction layer (). By adopting this configuration, the set state of a switch can be maintained with greater stability.
