A counter electrode having carbon compound layer for dye-sensitized photovoltaic cell and a method for manufacturing the same are provided to reduce a manufacturing cost and improve durability by forming the counter electrode using an adhesion layer and the carbon compound layer. A dye-sensitized photovoltaic cell comprises an optical electrode(10), a counter electrode(20) located to be faced to the optical electrode, an electrolyte(30). The counter electrode is formed by stacking the adhesion layer and a carbon compound layer(23) sequentially on a conductive substrate(21) for the counter electrode. The electrolyte is distributed uniformly within a metal oxide nano particle layer(12) as a porous film in a space between the optical electrode and the counter electrode.
