PROBLEM TO BE SOLVED: To provide a dye-sensitized solar cell in which an electrolytic solution can be arranged uniformly between both electrode faces without depending on viscosity, and in which damage of a connection part and deterioration of a dye due to heat in sealing can be suppressed. SOLUTION: The dye-sensitized solar cell 10 has a porous oxide semiconductor layer 3 on which the sensitized dye is carried. Moreover, this is provided with a first electrode 2 which functions as a window electrode, and a second electrode 5 arranged opposed to the first electrode by interposing an electrolyte layer 6 at least at one part. Furthermore, a first base material 1 at which the first electrode is installed and a second base material 4 at which the second electrode is installed are provided with at least a first region α pinching the electrolyte layer, and a second region β pinching an absorbent to absorb laser light, and the second region β is arranged so as to surround the first region α.
