PROBLEM TO BE SOLVED: To provide a method of efficiently cheaply forming a fine circuit having a resistivity causing no problem in practice, and a circuit board formed thereby. SOLUTION: The method of forming a circuit board comprises a step of coating an insulating board with a conductive paste containing metal grains of a mean grain size of 1-100 nm, a step of irradiating a circuit forming part with a light absorbable by the metal grains, and a step of removing the conductive paste from parts not irradiated with the light.
