Claim:
1. A dye-sensitized solar cell comprising: a first electrode; a second electrode that faces the first electrode; an electrolyte that is disposed between the first electrode and the second electrode; and a sealing portion that has an annular shape and surrounds the electrolyte together with the first electrode and the second electrode, and connects the first electrode and the second electrode, wherein at least one interface of a first interface between the first electrode and the sealing portion, and a second interface between the second electrode and the sealing portion constitutes a wide width section having the broadest sealing width among the sealing widths of the sealing portion, and the sealing portion has a narrow width section having a narrower sealing width than the wide width section, the sealing portion has a first resin sealing portion which is formed from a resin and is adhered to the first interface, and a second resin sealing portion which is formed from a resin and bonds the first resin sealing portion and the second interface, an inorganic sealing section consisting of an inorganic material is provided on at least one electrode of the first electrode and the second electrode, and within the sealing portion and the inorganic sealing section comprises a main body section that is provided on at least one of the first electrode and the second electrode, and a decreasing-thickness section that is provided on the electrolyte side or the opposite side of the electrolyte in the main body section, and the decreasing-thickness section has a thickness that decreases as the decreasing-thickness section is separated apart from the main body section, the thickness of the decreasing-thickness section being a thickness from the at least one of the first electrode and the second electrode on which the main body portion is provided.
