摘要：PROBLEM TO BE SOLVED: To provide a laser beam welding method capable of suppressing occurrence of degradation and dispersion of the welding quality. SOLUTION: In the laser beam welding method for bonding a core wire 11 to a metal terminal 13 by the welding, the core wire 11 is abutted on the metal terminal 13 while the core wire 11 is held by a first tool 12a and a second tool 12b and a metal terminal 13, and the core wire 11 is bonded to the metal terminal 13 by irradiating laser beams on the core wire 11 located between the first tool 12 and the second tool 12b. When a fore end side of the core wire is held by the first tool and the metal terminal, a space is formed between the first tool and the core wire or between the metal terminal and the core wire.
