Abstract

A line defect consists of a first straight line portion (3) formed along a straight line Y, a second straight line portion (4) formed along a straight line X intersecting the straight line Y perpendicularly from the vicinity of the end of the first straight line portion (3), and a curved line portion (5) connecting the ends in close proximity to each other of the first straight line portion (3) and the second straight line portion (4). The straight line portion (3) consists of a plurality of line defect columns where the centers of gravity of cross-section on an x-y plane including the straight lines X and Y are arranged on the straight line Y. The straight line portion (4) consists of a plurality of line defect columns where the centers of gravity of the cross-section are arranged on the straight line X. The curved line portion (5) consists of a plurality of line defect columns where the centers of gravity of the cross-section are arranged on a curved line connecting the center of gravity of cross-section of a line defect column closest to the intersection P of the straight lines X and Y out of the line defect columns constituting the straight line portion (3) and the center of gravity of cross-section of a line defect column closest to the intersection P out of the line defect columns constituting the straight line portion (4).
