Abstract
In the surface structure of an article 7 according to the present invention, a plurality of convex portions 11 are so disposed on a surface 9 as to have intervals relative to each other and a plurality of fine convex portions 21 having a diameter d and a height h smaller than those of the concave portion 11 are formed on the surface of at least the edge portion 15 of the concave portion 11. By this, when a hand touches the surface 9 of the article 7, the proper number of convex portions 21 abut on a linear object 25 constituting a fingerprint 23 of a hand's finger, to thereby allow the human being to obtain a delicate-and-soft touch feeling.
