A dye-sensitized solar cell comprises a pair of electrodes that face each other; an electrolyte that is disposed between the pair of electrodes; and a sealing section that connects the pair of electrodes and is provided around the electrolyte. In the dye-sensitized solar cell, the sealing section comprises at least one corner section when the sealing section is viewed in planar view from the electrode side, and a first contact surface at the corner section with at least one of the pair of electrodes comprises a first curve line-containing surface containing a curved curve line on the electrolyte side.
