Abstract
A laser welded joint improving the tensile shear strength without causing an increase in the welding time and without using an expensive remote laser head, that is, a laser welded joint obtained by arranging metal sheets overlaid and welding them by a laser beam from the overlaid direction, wherein when a total thickness of the metal sheets welded overlaid is 't' (mm), the width of the weld metal at the joined interface is 0.6t1/3+0.14 (mm) or more.
