Abstract:
1. A method for producing a circuit board provided with a plastic base and an electroconductive layer provided on the plastic base, the method comprising: a step of coating an electroconductive paste for electron beam curing on the plastic base, and a step of obtaining the circuit board by curing the electroconductive paste by irradiating with an electron beam to form an electroconductive layer, an electroconductive paste consisting of an electroconductive powder; a radical polymerizable composition consisting of a mixture of a bifunctional urethane-based oligomer, a monofunctional acrylate monomer, and polyethylene glycol diacrylate; and a plasticizer, the plasticizer being incorporated at a ratio of 5 parts by mass to 20 parts by mass based on 100 parts by mass of the radical polymerizable composition.
