A counter electrode for a dye-sensitive solar cell and a solar cell including the same are provided to improve the attachment of a noble metal layer by forming an adhesion layer between the noble metal layer and the transparent conductive layer of the counter electrode. A substrate(10) is coated with a transparent conductive layer(20). The transparent conductive layer is made of ITO(Indium Tin Oxide) or FTO(Fluorine Tin Oxide). An adhesion layer(30) is the conductive material layer and is interposed between the transparent conductive layer and a noble metal layer(40) to enhance the adhesion. The noble metal layer is positioned in the uppermost layer of the counter electrode and exchanges the electron by directly contacting the electrolyte.
