Abstract: A photosensitive resin composition includes: a copolymer obtained by subjecting a conjugated diene polymer having a (meth)acryloyl group, a conjugated diene monomer, and a (meth)acrylic acid monomer to copolymerization; a compound having at least one ethylenically unsaturated group; and a photoinitiator. The copolymer contains 60 wt % to 99 wt % of a copolymer fraction having a molecular weight ranging from 30,000 to 900,000, and 1 wt % to 22 wt % of a copolymer fraction having a molecular weight ranging from 1,000 to 10,000 when calculated from an integral molecular weight distribution curve obtained by plotting cumulative weight percentage versus molecular weight falling within a range between 1,000 and 1,000,000 measured by gel permeation chromatography.
