Resistance change in 2 dimensional conductive film (very thin film) shows an irregular characteristic with increasing of the film thickness. The evidences are shown in the attached paper (in English). In this paper, it is simply expressed that the phenomenon occurs by the interference of two electron paths that are introduced from a solution of Schrodinger equation. In this paper, the solution method is expressed in detail: Initially, it was assumed that an electron path in a thin conductive film is expressed by a Schrodinger equation whose trajactory is impinged by a periodic potentials. To solve the equation, some calculated results that had been reported on literatures were referred. Based on these equations, the final solution was obtained as a simple sinusoidal function after used some new boundary conditions. This proved that an electron path in a thin film is expressed by the sinusoidal function. Therefore, when two electron paths are exists in a film, there occurs an interference with each other, and the result appears as an irregular phenomenon of a resistance.
