Abrasive pad

Abstract

An abrasive pad having an abrading part and a groove part on an abrasive surface is provided in which a surface of the groove part has a non-foamed part, and a foamed part is exposed on a surface of the abrading part.

What is claimed is: 
     
         1 . An abrasive pad comprising an abrading part and a groove part on an abrasive surface, wherein
 a surface of the groove part comprises a non-foamed part, and a foamed part is exposed on a surface of the abrading part.   
     
     
         2 . The abrasive pad according to  claim 1 , wherein
 a maximum height roughness (Rz) of the surface of the groove part is 10 μm to 30 μm, and a maximum height roughness (Rz) of the surface of the abrading part is 30 μm to 100 μm.   
     
     
         3 . The abrasive pad according to  claim 1 , wherein
 an arithmetic mean roughness (Ra) of the surface of the groove part is 0.1 μm to 10 μm, and an arithmetic mean roughness (Ra) of the surface of the abrading part is 10 μm to 45 μm.   
     
     
         4 . The abrasive pad according to  claims 1 , wherein
 a value of (the maximum height roughness (Rz) of the surface of the abrading part)−(the maximum height roughness (Rz) of the surface of the groove part) is 20 μm to 70 μm.   
     
     
         5 . The abrasive pad according to  claims 1 , wherein
 a value of (the arithmetic mean roughness (Ra) of the surface of the abrading part)−(the arithmetic mean roughness (Ra) of the surface of the groove part) is 5 μm to 35 μm.   
     
     
         6 . The abrasive pad according to  claims 1 , comprising a resin foam formed from a thermoplastic resin that has a three-dimensional bubble structure, wherein
 the thermoplastic resin is at least one type of resin selected from a group of polyphenylene sulfide resin, polyethylene terephthalate resin, and polycarbonate resin.
