PROBLEM TO BE SOLVED: To provide a photosensitive resin composition excellent in tent film strength and deformed through hole reliability without impairing sensitivity, resolution, adhesion to a substrate, resist removability, etc. SOLUTION: The photosensitive resin composition contains a binder resin (A), an ethylenically unsaturated compound (B) and a photopolymerization initiator (C), and the component (B) contains an acrylic compound having urethane bonds represented by formula (1) (where R is H or a 1-3C alkyl; R1 and R2 are each a 2-5C alkylene; X is a 2-20C divalent hydrocarbon, the symbols X are different or identical; Y is a divalent group obtained by removing H atoms from both OH groups of bisphenol; m, m', n and n' are each an integer of 0-30; and l and l' are each an integer of 1-10). |
