摘要

[Problems] Provided are a photoelectric conversion element manufacturing method and the like which is capable of easily manufacturing a photoelectric conversion element including a terminal that is strongly bonded to an electrode made using titanium. [Means to solve the problems] A method of manufacturing a photoelectric conversion element 100 includes: a semiconductor forming step of forming a porous oxide semiconductor layer 3 on a surface of a catalytic layer 6 of a first electrode 10 including a metal plate 4 made of titanium or an alloy including titanium and the catalytic layer 6, or a surface of a transparent conductor 1 of a second electrode 20 including the transparent conductor 1; a dye supporting step of supporting a photo-sensitized dye on the porous oxide semiconductor layer 3; a sealing step of surrounding and sealing the porous oxide semiconductor layer 3 and an electrolyte 5 between the first electrode 10 and the second electrode 20 with a sealing material 14; and a terminal forming step of forming a terminal 7 on the metal plate 4. In the terminal forming step, the terminal 7 is formed by applying an ultrasonic wave to a high-melting-point solder while the high-melting-point solder is heated to melt.
