Abstract

A variable resistance element is formed by sandwiching a metal oxide layer whose resistance changes between a pair of electrodes and the metal oxide layer includes a pair of variable resistance layers whose resistances change by formation of a current path and a branching suppression layer which is sandwiched between the variable resistance layers and suppresses branching of the current path.
