Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a process capable of efficiently and securely producing a porous polyimide film. SOLUTION: The process for producing the porous polyimide film is characterized by including a process for forming a coating film using a coating liquid containing (a) a polyimide precursor obtained by reacting a tetracarboxylic acid anhydride with a diisocyanate compound and/or (b) a polyimide fine particle obtained by carrying out imidation of the precursor.
