(57) [PROBLEMS] To provide a photosensitive resin composition which is excellent in sensitivity at the time of exposure and adhesion to a substrate at the time of development, and which does not cause precipitation and decrease in sensitivity when the photosensitive resin composition is stored at room temperature. Provided is a negative heat-resistant photosensitive resin composition containing a mercaptotetrazole compound. SOLUTION: (A) a 5-mercaptotetrazole compound having a bulky functional group at the 1-position, (B) a polyimide precursor, a polybenzoxazole precursor, or a copolymer thereof, and (C) photopolymerization initiation A photosensitive resin composition containing an agent and (D) a diluting solvent. |
