A switching element is of a configuration that includes: an ion conduction layer ( 40 ) for conducting metal ions, a first electrode ( 21 ) and a second electrode ( 31 ) provided in contact with the ion conduction layer, a third electrode ( 35 ) that can supply metal ions to the ion conduction layer, and a diffusion prevention layer ( 90 ) provided between the ion conduction layer ( 40 ) and the third electrode ( 35 ) for preventing the diffusion of metal ions from the third electrode ( 35 ) to the ion conduction layer ( 40 ). By adopting this configuration, the set state of a switch can be maintained with greater stability.
