Claim:
A PVD cylindrical target, comprising: a cylindrical substrate; and an evaporation material covering the outer circumferential surface of said substrate, wherein said evaporation material is more brittle than Cr, wherein the PVD cylindrical target includes a meshing part consisting of at least either of a protruding shape and a recessed shape at the interface between said substrate and said evaporation material, and at least either of the protruding shape and the recessed shape is formed with a rounded angular part having a curvature radius of 0.5 mm or more, wherein said protruding shape includes a protruding streak, and said recessed shape includes a recessed streak, formed over the circumferential direction of the substrate, wherein said meshing part is formed in a bellows shape in which the protruding streak and the recessed streak are alternately continuously disposed in the axial direction of the substrate, and wherein a pitch of said recessed streak is set to 1 mm or more and 20 mm or less, an interval between the apex of the protruding streak and the bottom of the recessed streak is set to 0.5 mm or more and 5 mm or less, an inclination of a slant face connecting the protruding streak with the recessed streak is set to 80° or less to an axial center of said substrate.
