Abstract (en)
To provide a lap structure of a lapping tool which is superior in wear and abrasion resisting property and maintains a lap shape for a long period of time without requiring any correction working. The lap structure of a lapping tool of the wet type wherein lapping is performed for a surface of a work using abrasion grain to finish the surface of the work is constructed such that a particle holding layer 11 wherein a particle holding member 12 softer than the abrasion grain 14 embeds and holds hard particles 13 in a substantially uniformly dispersed condition is formed on a lap surface, that a surface of the particle holding layer 11 is polished so that flat surfaces of the hard particles 13 polished together are exposed to the surface of the particle holding layer 11, and that the abrasion grain is held on the surface of the particle holding member 12 between the exposed hard particles 13. <IMAGE>
