Provided are a dye-sensitized solar cell wherein a counter electrode composed of a stable counter electrode conductive layer and a catalyst layer is formed on a porous insulation layer, and a dye-sensitized solar cell module wherein the dye-sensitized solar cell is utilized. A dye-sensitized solar cell includes a supporting body made of a light-transmissive material, and a laminate wherein a conductive layer, a photoelectric conversion layer having a porous semiconductor layer with a dye adsorbed therein, a porous insulation layer, a counter electrode conductive layer, and a catalyst layer are laminated in the order presented. The photoelectric conversion layer and the porous insulation lay are filled with a carrier transport material.

In a lithium-ion secondary battery of the present invention, the electrical resistivity of the mixture of a positive electrode active material, an electrically conductive member, and a binder is 0.1 &#x3a9;cm or more but 1 &#x3a9;cm or less. The positive and negative electrodes each have an electrical capacity of 10 mAh or more but 50 mAh or less per volume of a rectangular parallelepiped that has a 1 cmsquare base on a face of the electrode of one polarity facing the electrode of the other polarity and that has a height equal to the thickness of the electrode of the one polarity at the square base. Used as the negative electrode thereof is a negative electrode formed by sintering graphite powder, non-graphitizing carbon, and fibrous powder retained in the pores of a porous metal structure in an inert gas atmosphere at a temperature of between 600 and 1000&#xb0; C.
