To provide a dye-sensitized solar cell in which no member other than a sealing material is used in the sealing part to seal an electrolyte layer, and which has a large durability against a thermal expansion or the like of a substrate due to temperature changes.

A recess groove is formed against a fixed part of each substrate in which the sealing material is fixed, and the sealing material is filled into this recess groove and fixed. Since the sealing material is filled into the recess groove, side walls of the recess groove execute a function as an anchor against the sealing material even if an opposing force is applied against a face direction of respective substrate, so that a separation of the fixed part between the sealing material and the respective substrate is inhibited. By this, a liquid leakage from the electrolyte layer is hard to occur, and even if the dye-sensitized solar cell thus formed is expanded or shrunk by the thermal changes or the like, the high durability can be obtained.
