Abstract

A laser welded joint has weld metal provided between a plurality of steel sheets. A chemical composition of the weld metal has predetermined components, and average hardness of the weld metal is 350 to 540 in Vickers hardness. In the weld metal, distribution density of porosities having a diameter of 2 μm to 50 μm is equal to or less than 5.0 pieces/mm. In the weld metal, distribution density of oxide inclusions having a diameter of 3 μm or more is 0.1 to 8.0 pieces/mm.
