Abstract:
1. A method of manufacturing a circuit board, the method comprising: forming an intaglio pattern corresponding to a circuit pattern by selectively forming a resist on a mold board; filling conductive material in the intaglio pattern; transferring the conductive material onto a carrier by pressing the carrier onto the mold board such that one surface of the carrier faces the surface of the mold board having the conductive material filled in, an adhesive layer which comprises thermoplastic adhesive being formed on the one surface of the carrier; transcribing the conductive material into an insulation board by pressing the insulation board onto the carrier such that the insulation board faces and contacts the surface of the carrier having the conductive material transferred thereto, the conductive material being buried in the insulation board and the adhesive force of the adhesive layer to the conductive material being decreased by hot-pressing the insulation board onto the carrier; and separating the carrier along with the adhesive layer from the insulation layer.
