Welded joint

A welded joint comprising:

• a first steel sheet and a second steel sheet connected to a weld bead part whose extension direction is set as a long side in plan view, wherein:
• the first steel sheet and the second steel sheet each have a heat-affected zone located around the weld bead part, and a non-heat-affected zone not affected by heat due to welding;
• at least either the first steel sheet or the second steel sheet has a base iron and a plating layer on the base iron in the non-heat-affected zone;
• the plating layer is a plating layer having a chemical composition containing, by mass %,
• Al:
• 30.00 to 70.00%
• Mg:
• 7.00 to 20.00%
• Fe:
• 0.01 to 15.00%, and
• selectively containing one or more of an element group A, an element group B, an element group C, an element group D, an element group E, an element group F, and an element group G described below, with the balance composed of Zn of 5.00 mass % or more and impurities;
• and
• when viewed from a toe defined in JIS Z3001 (2018) toward a direction being orthogonal to the extension direction and separating from the toe, the toe, a region where the heat-affected zone or the base iron is exposed, and a region having the plating layer are configured in this order, and an average area ratio of an Fe—Al metal structure is 0 to 95%, an average area ratio of a Mg—Zn metal structure is 5 to 100%, and an average area ratio of an i-Zn phase is 3 area % or less in the plating layer when a cross section cut in a direction orthogonal to the extension direction is observed by a scanning electron microscope regarding a region, with an end portion of the plating layer closest to the toe set as a starting point, in a range from the starting point to 100 μm,
