A dye-sensitized solar cell comprising a negative electrode structure 20 and an opposing electrode structure 21 having a transparent conducting substrate, the negative electrode structure 20 having a metal substrate 25 and an semiconductor oxide layer 29 formed on the metal substrate 25 and carrying a dye 30. A chemical conversion treatment film 27 is formed on the surface of the metal substrate 25, and the semiconductor oxide layer 29 is formed on the chemical conversion treatment film 27. The solar cell generates electricity upon being irradiated with light from the side of an electrode opposing the negative electrode structure 20, prevents a decrease in the curvature factor (FF) caused by an increase in the size of the cell and a decrease in the conversion efficiency, features excellent durability, maintains a stable conversion efficiency over extended periods of time and improves the problem of rectification barrier.
