Abstract:
1. A manufacturing method for a circuit comprising: forming an insulating layer by: applying a polymeric material, which has been diluted with a solvent and filled with inorganic filler, to a base for resin application that includes a polymeric mold; and drying the polymeric mold; creating a circuit formation pattern and a via hole in the insulating layer by a laser treatment, which induces at least one of a positive potential and a conductive state in the circuit formation pattern and the via hole; and forming a circuit solely by plating the circuit formation pattern and the via hole; and repeating the insulating layer formation step, circuit formation pattern creation step and the circuit formation step a plurality of times in the recited order, in order to completely form the circuit, wherein the inorganic filler is glass in a granular form or ceramic in a granular form having a diameter of from 0.1 μm to 10 μm of which the amount added to the polymeric material is from 10 wt. % to 50 wt. %, and wherein the laser has a wavelength of 600 nm, or less, and the total energy of irradiated laser is from about 10 J/cm
