Abstract

[Problem to be solved] Providing a welded workpiece with decreased weld deformation, fuel injection valve equipped with the welded workpiece, and a laser welding method. [Means to solve the problem] A welded workpiece comprising: a first workpiece to be welded 1 with a hollow 13, a second workpiece to be welded 2, and a weld bead 3 formed by deep penetrating type laser welding, using emission of a laser beam from the side of the first workpiece to be welded after the first workpiece to be welded and the second workpiece to be welded are piled up, wherein a surface width of the weld bead is W1, a penetrating width as a width of the weld bead on the boundary surface of piled the first and the second workpiece to be welded is W2, a board thickness of the first workpiece to be welded is t, a ratio of WI / t of the surface width W1 and the board thickness t is smaller than the first threshold value, and a ratio (W1 - W2) / t of a difference between the surface width W1 and the penetrating width W2 and the board thickness t is smaller than the second threshold value.
