Abstract: A laser welding apparatus capable of eliminating or reducing a possibility that a part of air flows upward and hence fumes adhere to its protective optical member is provided. A laser welding apparatus according to the present disclosure includes a protective optical member disposed between a laser scanner and a workpiece, an upper-side gas supply unit, and a lower-side gas supply unit disposed below the upper-side gas supply unit. The protective optical member includes a plate-like part and a cylindrical part extending downward from an outer edge of the plate-like part. The upper-side gas supply unit is disposed below the plate-like part of the protective optical member. The upper-side gas supply unit includes a plurality of first ejection ports configured to eject gas to a center of the plate-like part, and a plurality of second ejection ports configured to eject gas downward with respect to the plate-like part.
