Abstract
In a plane including the center line of a vertical through hole, it is assumed that a segment that connects a first point corresponding to the edge of an opening of an insulating layer and a second point corresponding to the edge of a second opening is a first segment, a segment that connects the second point and a third point corresponding to an intersection point between the second opening and a surface of the insulating layer is a second segment, and a segment that connects the third point and the first point is a third segment. In the insulating layer, the first area located on one side with respect to the first segment is larger than the sum of the second area surrounded by the first, the second and the third segments and the third area located on the other side with respect to the third segment.
