A leaf seal for sealing a shaft rotating about an axis, in particular in a gas turbine, includes a multiplicity of spaced-apart leaves ( 26 ) which are arranged in a concentric circle around the axis and are fixed in their position by welded connections produced by electron beam welding, the leaves ( 26 ), with their surfaces, being oriented essentially parallel to the axis. The welded connections of the leaves are improved by the leaves ( 26 ) being designed in such a way and being arranged in the leaf seal in such a way that they abut against one another at the side edges directly or via intermediate spacers ( 27 ) along at least one contact line ( 36 ) extending over a plurality of leaves ( 26 ), and by the welded connections being designed as welds directed along the at least one contact line ( 36 ) and oriented in axial direction.
