The stack is heated and subjected to pressure in vacuum, and the metal foil, insulator and circuit board are thereby brought into tight contact with one another and laminated. The laser irradiation point on a conductor layer desired to be laser-processed on the laser irradiation side is subjected to a process 6 to increase the rate of the absorption of laser the diameter of which is equal to or smaller that laser irradiation diameter. Thereby it is possible to melt the conductor layer to form a hole there using low energy.  In order to form a hole 4, a hall 18 is irradiated with laser 3 in a desired position, and thus the metal foil as conductor layer and the insulator as insulator layer are melted and sublimed to form the hole.
