    Abstract: The present invention provides a lap fillet arc welding joint including a first metal sheet, a second metal sheet, and a weld bead. A region of the first metal sheet on one end side is bent. In a cross-sectional view in a cross section perpendicular to a weld line of the weld bead, in a first direction, a position of a tip end of the bent region of the first metal sheet overlaps a region of the second metal sheet on one end side. In a second direction, an amount of deviation between a central axis of a region connected to the bent region of the first metal sheet and a central axis of the region of the second metal sheet on one end side is ½ times or less of the average value of sheet thicknesses of the first metal sheet and the second metal sheet. A joint portion length, which is a length from a root portion of the second metal sheet to a weld toe portion of the first metal sheet, is two times or more of the sheet thickness of the second metal sheet.
