A positive photosensitive resin composition comprising 100 parts by weight of a polyamide derivative represented by the following formula (1), 5 to 30 parts by weight of a photosensitive compound containing a diazonaptol compound, and 10 to 50 parts by weight of a novolak resin is disclosed. (One) (In Formula (1), R 1 , R 2 , R 4 and R 5 are each independently a divalent to hexavalent acyl group having at least 2 carbon atoms, and R 3 is a hydrogen atom or an alkyl group having 1 to 10 carbon atoms. and k are each independently an integer of 10 to 1000, l is an integer of 1 to 1000, n and m are each independently an integer of 0 to 2 (where n + m> 0), and X is 2 to C 30 carboxyl groups.) |
