Abstract
Provided is a cutting method for a glass sheet, comprising radiating a laser beam to a cutting portion (C) of a glass sheet (G) having a thickness of 500 μm or less to fuse the glass sheet (G), wherein a narrowest gap between fused end surfaces (Gaand Gb) of the glass sheet (G), which face each other in the cutting portion (C), is managed to satisfy a relationship of 0.1≦b/a≦2, where 'a' is a thickness of the glass sheet (G) and 'b' is the narrowest gap.
