The present invention provides a photopolymerizable resin composition which is excellent in resolution and adhesion to a substrate and suitable for a photosensitive film. (A) It has an aromatic hydrocarbon group or / and an alicyclic hydrocarbon group in the side chain, an acid value of 80 to 200 mgKOH / g, and a weight average molecular weight of 20,000 to 100,000. (B) a compound having at least two ethylenically unsaturated bonds and a weight average molecular weight of less than 20,000, (c) having one ethylenically unsaturated bond and aromatic carbonization A compound having a hydrogen group or / and an alicyclic hydrocarbon group and having a weight average molecular weight of less than 20,000, and (d) a photopolymerization initiator, comprising (a) component, (b) component and (c ) When the total content of the components is 100% by mass, the content of the component (c) is 1 to 10% by mass.
