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 mum or less to fuse the glass sheet (G), wherein a narrowest gap between fused end surfaces (Ga1 and Gb1) 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.
