This study describes the damage around the drilled hole wall in small diameter drilling of GFRP for a printed wiring board in order to prevent from ion migration. In the present report, investigation was carried out from the view of the relative positions between hole center and plain woven cloth. Specially, we paid attention to the radius of the drill and the width of cloth. As results, it is clear that there are two important factors of internal damage widths around the drilled hole; the relative angles between cutting directions and fiber directions, and thickness of glass cloth at the drilled hole wall.
