Abstract
Provided are a variable resistive element having a configuration that the area of an electrically contributing region in a variable resistor body is smaller than the area defined by an upper electrode or a lower electrode, and a method for manufacturing the variable resistive element. The cross section of a current path, in which an electric current flows through between the two electrodes via the variable resistor body at the time of applying the voltage pulse to between the two electrodes, is formed with a line width of narrower than that of any of the two electrodes and of smaller than a minimum work dimension regarding manufacturing processes, so that its area can be made smaller than that of the electrically contributing region in the variable resistive element of the prior art.
