PROBLEM TO BE SOLVED: To provide a dye-sensitized solar battery which allows the increase in the power generation efficiency even with the reduction in the aperture ratio sufficiently held down. SOLUTION: A dye-sensitized solar battery 100 comprises: a work electrode 1 having a transparent substrate 5, a transparent conductive film 6 provided on the transparent substrate 5, a wiring part W provided on the transparent conductive film 6, and a porous semiconductor layer 8 provided on the transparent conductive film 6; a counter electrode 2 opposed to the work electrode 1; and an electrolyte 4 disposed between the work electrode 1 and the counter electrode 2. The wiring part W has a current collecting electrode 7A. The current collecting electrode 7A has current collector units 10A-10D. The current collector units 10A-10D each have a filamentous current collecting part 11, a first wiring line 12A disposed to run slantwise with respect to a lengthwise direction of the current collecting part 11, and a second wiring 13 placed between the current collecting part 11 and the first wiring 12A and connected with the current collecting part 11.
