Abstract
A nonlinear device of the present invention includes: a first electrode and a second electrode at least partially opposing each other; and a nonlinear resistant layer made of a material mainly containing zinc sulfide, formed so as to be in contact with the first electrode and the second electrode, wherein at least one of the first electrode and the second electrode is made of an electrode material satisfying a relationship .DELTA.G.sub.M -.DELTA.G.sub.Zn >0, where .DELTA.G.sub.M is standard free energy of a generation reaction of a sulfide of the electrode material and .DELTA.G.sub.Zn is standard free energy of a generation reaction of a sulfide of zinc.
