It is an object of the present invention to provide a dye-sensitized solar cell with high cell performance. The present invention is related to a dye-sensitized solar cell comprising, as constituent elements, a semiconductor electrode with a sensitizing dye adsorbed thereon, a charge transfer layer and a reference electrode, said reference electrode satisfies the relation b > a, where a (mA) denotes the oxidation-reduction electric current value difference in a negative potential region of not lower than -0.7 V but lower than 0 V and b (mA) denotes the oxidation-reduction electric current value difference measured in a positive potential region of 0 V to 0.7 V, said oxidation-reduction electric current value difference are measured by cyclic voltammetry, with the oxidation-reduction potential of ferrocene as a standard.
