PROBLEM TO BE SOLVED: To obtain a photocurable resin composition which minimizes the VOC issue, is water-swellable and water-developable, and gives a cured material with excellent electric properties and to provide a curing method for the composition. SOLUTION: (1) The photocurable resin composition comprises (A) a photopolymerizable resin containing an acidic group, (B) a photopolymerizable resin having a polymerizable unsaturated group and an onium salt, (C) a reactive monomer, and (D) a photopolymerization initiator. (2) The photocurable resin composition is the one described in (1) in which the acid value of (A) is 30-500 mgKOH/g, and the compounding ratio of (A) to (B) is 50:50-10:90. The photocurable resin composition described in (1) or (2) is applied and cured by light treatment and/or heat treatment. COPYRIGHT: (C)2004,JPO
