When a photosensitive resin composition layer made of a photosensitive resin composition is formed on a substrate, the photosensitive resin composition layer has a small tackiness, excellent workability, and is capable of alkali development with high resolution. Also provided are a photosensitive resin composition capable of forming a cured film with small warpage and excellent flexibility after curing, and capable of imparting flame retardancy, and a photosensitive element using the same. (A) an acrylic resin, (B) a polyurethane resin, (C) a photopolymerizable compound having at least one ethylenically unsaturated group in the molecule, (D) a photopolymerization initiator, E) a phosphorus-containing compound, wherein the polyurethane resin (B) is an epoxy acrylate compound having an ethylenically unsaturated group and two or more hydroxyl groups, a diisocyanate compound, A photosensitive resin composition represented by a reaction product with a diol compound having a carboxyl group.
