ABSTRACT:
According to an embodiment of the present invention, a method of producing an electronic circuit comprises printing first metal-containing resin particles which consist of at least a thermosetting resin and fine metal particles and second metal-containing resin particles which consist of at least a thermoplastic resin and fine metal particles by electrophotography to form a first base pattern which consists of the first metal-containing resin particles and a second base pattern which consists of the second metal-containing resin particles on a substrate; forming a first metal conductor layer on the first and second base patterns; forming a second metal conductor layer on the first metal conductor layer by electrolytic plating by supplying electric current to the first metal conductor layer; and removing the second base pattern and the first and second metal conductor layers which are formed on the second base pattern.
