Textured structure for object surface

Abstract

A textured structure is formed on the surface of an object. The textured structure is composed of first convexities formed on the surface of the object, and second convexities formed between the first convexities. The second convexities are formed to be smaller in width than the first convexities, and equal to or smaller than the first convexities in height.

1 . A textured structure for an object surface, comprising: 
 a plurality of first convexities formed on a surface of an object so as to be separated from each other; and    a plurality of second convexities formed between the first convexities, wherein    the second convexities are smaller in width than the first convexities, and are either equal in height to the first convexities or are smaller in height than the first convexities.    
   
   
       2 . The textured structure of  claim 1 , wherein the second convexities comprise pressure-receiving links that are formed so as to link adjacent first convexities to each other.  
   
   
       3 . The textured structure of  claim 1 , wherein the second convexities comprise island-shaped pressure-receiving parts that are not in contact with the first convexities.  
   
   
       4 . The textured structure of  claim 1 , wherein the first convexities are formed in rows.  
   
   
       5 . The textured structure of  claim 1 , wherein the first convexities are formed so as to have various different shapes and sizes in a plan view.
