Abstract: Provided is a photoelectric conversion device which is capable of improving utilization efficiency of dye, a method for manufacturing the same, a dye adsorption device, a liquid retaining jig used for the dye adsorption device, and a method for manufacturing a photoelectric conversion element. The photoelectric conversion device includes a conductive base material, a porous semiconductor layer which is disposed on the conductive base material and onto which dye is adsorbed, a counter electrode, an electrolyte layer, a sealing material that is formed at the periphery of the conductive base material, and at least one protrusion formed between the porous semiconductor layer and an outer periphery of the sealing material.

Abstract: Disclosed herein is a die manufacturing method including the steps of: forming a pattern on the machining surface of a cylindrical resin original plate by laser machining; and fabricating a cylindrical die by the electroforming method using the resin original plate having the pattern formed.
