The present invention provides a method for manufacturing a photoelectric conversion element having high photoelectric conversion efficiency by a simple method. A method for manufacturing a photoelectric conversion element (1) includes: a formation step for forming a hole transport layer (7) containing a hole transport material by adhering the hole transport material to one of a light absorption layer (6) and a conductive layer (8); a melting step for heating the hole transport layer (7) to a temperature equal to or higher than the melting point of the hole transport material and equal to or higher than 120 DEG C and equal to or lower than 170 DEG C to melt the hole transport layer (7); and a bonding step for bonding the light-absorbing layer 6 and the conductive layer 8 via the hole transport layer 7 by cooling while pressing the other of the light-absorbing layer 6 and the conductive layer 8 onto the molten hole transport layer 7. The light-absorbing layer 6 contains a compound represented by general formula (1). In general formula (1), A is an organic molecule, B is a metal atom, and X is a halogen atom. [Chemical Formula 1] ABX3 (1).
