Abstract: It is an object of the present invention to provide a dye-sensitized solar cell, etc. capable of preventing, even when a highly-conductive electrolyte is employed, a short circuit between a transparent conductive film of a working electrode and the electrolyte, and thereby enhancing reliability with improved photoelectric conversion characteristics and improved durability. A short circuit-prevention layer is patterned in a frame shape so as to surround the periphery of a dye-supported metal oxide layer on a region of a conductive surface where the dye-supported metal oxide layer is not formed. The short circuit-prevention layer is formed to be thinner than the dye-supported metal oxide layer, and the dye-supported metal oxide layer is formed so as to cover the conductive surface in the frame of the short circuit-prevention layer and to extend onto the short circuit-prevention layer.
