Zusammenfassung:	Provided is a spiny liner that may further improve bonding strength when being integrated with metal on the outer peripheral surface side. The spiny liner includes a plurality of projections including constricted projections on the surface. Denoting the number of constricted projections per 100 mm2 out of the projection by Pc, the average height of projections by h (mm), and the average of maximum thicknesses and the average of minimum thicknesses of any 20 projections out of the constricted projections by dw (mm) and dn (mm), respectively, the total value of (I) and (II) below is 1.55 or more. I=Pc×0.35hπ/12×2dw2−dw×dn−dn2II=Pc×dn2/4×π×0.35h
