A driver circuit facilitates reducing noises and losses and improving the driving performances thereof without connecting a series circuit of capacitor and a resistor to the gate of IGBT. The driver circuit includes a slope setting circuit that sets the gate voltage waveform of IGBT; and an operational amplifier that includes a non-inverting input terminal, to which an output voltage V* from slope setting circuit is inputted, and an inverting input terminal, to which a divided voltage Vgsf divided by resistors is inputted; and the operational amplifier outputs an output voltage Vout, proportional to the difference between the output voltage V* and the divided voltage Vgsf, to the gate of IGBT.

A composite material obtained by laminating (A) a layer formed of an epoxy resin curing composition including a polyamide compound having a structure containing a phenolic hydroxyl group represented by the following formula (I) or (II) in its repeating unit and (B) a layer of a polyimide to each other. The composite material is preferably obtained by applying the epoxy resin curing composition to at least one side of a polyimide film or sheet. In formula (I), ring A and R each represent an arylene group having 6 to 18 carbon atoms, an alkylidenediarylene group having 13 to 25 carbon atoms, etc. In formula (II), ring B is an arylene group having 6 to 18 carbon atoms or an alkylidenediaryl group having 13 to 25 carbon atoms.

A metal layer 18 is sandwiched between insulating layers 14 and 20 so that required strength is maintained. Hence it follows that the thickness of a core substrate 30 can be reduced and, therefore, the thickness of a multi-layer printed circuit board can be reduced. Formation of non-penetrating openings 22 which reach the metal layer 18 in the insulating layers 14 and 20 is simply required. Therefore, small non-penetrating openings 22 can easily be formed by applying laser beams. Thus, through holes 36 each having a small diameter can be formed.

The apparatus for manufacturing a wiring substitute comprises a transporter having a circuit where a sheet is circulated; a screen printer for printing a conductive paste on the sheet; a counter for counting the number of times to print the conductive paste on the sheet; and a distributor for ejecting the sheet from the circuit when the counted number reaches a preset number. Thus, the conductive pillars having uniform properties can be formed automatically on the conductive foil with high productivity.
