The glass sheet cutting device (1) includes a first laser irradiator (2) for radiating a fusing laser beam (LB1) and a second laser irradiator (3) for radiating an annealing laser beam (LB2). Through a fusing gap (S) formed between fused end surfaces (Ga1, Gb1) by fusing, the second laser irradiator (3) radiates the annealing laser beam (LB2) obliquely from above onto the fused end surface (Ga1) to be annealed.
