Zusammenfassung:	A butt-welded joint includes a pair of steel plates (1), a first weld metal (2) that is fo1med at a butting portion of the pair of steel plates (1) from a first surface side (1A) of the pair of steel plates (1) to a second surface side (1B) opposite the first surface side (1A) by irradiation of a first high-energy density beam from the first surface side, and a second weld metal (3A) that is formed by a second high-energy density beam to cover an end surface of the first surface side of the first weld metal (2). Here, a width W1 of the first weld metal (2) on the first surface and a width W2 of the second weld metal (3A) on the first surface satisfy a following equation (1), and a depth from the first surface of the second weld metal (3A) is 2.0 mm to 10.0 mm. l.2? W2/W1?3.5 ???(1)
