Zusammenfassung:To provide an alkali-developable photocurable resin composition that has excellent developability and allows for long-term shipping, a cured product, and a printed wiring board.SOLUTION: An alkali-developable photocurable resin composition contains a resin having a novolac skeleton and containing a carboxy group, a copolymer resin containing a carboxy group, a photopolymerization initiator, a photopolymerizable monomer, and spherical filler. The content of the spherical filler is 40 vol.% or more relative to the total volume of the alkali-developable photocurable resin composition,.SELECTED DRAWING: None 【課題】現像性が良好であり、長期船便輸送が可能であるアルカリ現像型の光硬化性樹脂組成物、硬化物、およびプリント配線板の提供。【解決手段】ノボラック骨格を有し、カルボキシ基を含有する樹脂と、カルボキシ基を含有する共重合樹脂と、光重合開始剤と、光重合性モノマーと、球状フィラーと、を含有するアルカリ現像型の光硬化性樹脂組成物であって、前記球状フィラーの含有量が、前記アルカリ現像型の光硬化性樹脂組成物全体に対して、40体積%以上である。【選択図】なし
