A photosensitive insulating resin composition that suppresses warpage and elongation of a substrate when forming an insulating film and has excellent resolution, sensitivity, electrical insulation, and the like, and the composition is cured. A cured product such as an insulating film and a method for manufacturing the insulating film are provided. The photosensitive insulating resin composition of the present invention comprises (A) an alkali-soluble resin containing a structural unit (a1) derived from a crosslinkable monomer and a structural unit (a2) having a phenolic hydroxyl group; (B) A crosslinking agent, (C) a photosensitive compound, and (D) a solvent are contained.
