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.

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.
