Abstract
A method for manufacturing a wiring board includes preparing a large-sized wiring board having an effective region and a dummy region such that the board has a penetrating hole on a border of the effective and dummy regions and an inner-hole conductive layer covering an inner surface of the penetrating hole, moving a rotary tool having a tip blade along rotation axis at a peripheral portion of the penetrating hole such that the rotary tool drills a hole into the board at the peripheral portion and segments the conductive layer into portions in the effective and dummy regions, and moving a rotary tool having a side blade in a direction perpendicular to rotation axis such that the dummy region is cut off from the effective region after the rotary tool having tip blade makes the hole and a wiring board having the effective region of the board is formed.
