    Abstract: PROBLEM TO BE SOLVED: To provide a negative heat-resistant photosensitive resin composition excellent in sensitivity in exposure and adhesiveness to a substrate in development and containing a 5-mercaptotetrazole compound free of precipitation and lowering of sensitivity when the photosensitive resin composition is stored at room temperature. SOLUTION: The photosensitive resin composition comprises (A) a 5- mercaptotetrazole compound having a bulky functional group in the 1-position, (B) a polyimide precursor, a polybenzoxazole precursor or a copolymer of these, (C) a photopolymerization initiator and (D) a diluting solvent.
