A tin layer and a zinc layer are stacked sequentially on a given substrate to form a multilayered film composed of the tin layer and the zinc layer. Then, the multilayered film is heated to a given temperature to form a tin-zinc alloy film through the diffusion of the tin elements of the tin layer into the zinc layer.
