Abstract
Official abstract text for this publication.
Disclosed is a surface structure of an article ( 1 ) including multiple protrusions ( 3 ) on the surface. A height H of the protrusions ( 3 ) is equal to or larger than 5 μm, and equal to or smaller than 32 μm, as well as at least one of a distance P between each two neighboring protrusions ( 3 ) and a distance W between each neighboring two of recesses ( 5 ) formed between the protrusions ( 3 ) is larger than the height H of the protrusions ( 3 ).
First claim
Opening claim text (preview).
The invention claimed is: 1. A surface structure of an article comprising, on an exposed surface, a plurality of hemispherical protrusions satisfying conditions (1), (2), and (3) given below: (1) a height H of the protrusions is equal to or larger than 5 μm, and equal to or smaller than 32 μm; (2) a ratio H/P between the height H of the protrusions and a distance P between centers of two neighboring protrusions is in a range of 1/5 to 1/2, and (3) a frictional coefficient between a human finger and the exposed surface is within a range of 0.55±0.15. 2. A surface structure of an article comprising, on an exposed surface, a plurality of hemispherical protrusions satisfying conditions (1), (2), and (3) given below: (1) a height H of the protrusions is equal to or larger than 5 μm, and equal to or smaller than 32 μm; (2) a ratio H/W between the height H of the protrusions and a distance W between centers of two neighboring recesses formed between the protrusions is in a range of 1/5 to 1/2, and (3) a frictional coefficient between a human finger and the exposed surface is within a range of 0.55±0.15. 3. The surface structure of claim 1 , wherein: at least one of the distance P between the centers of two neighboring protrusions or a distance W between centers of two neighboring recesses formed between the protrusions is larger than the height H of the protrusions. 4. The surface structure of claim 2 , wherein: at least one of a distance P between centers of two neighboring protrusions or the distance W between the centers of two neighboring recesses is larger than the height H of the protrusions. 5. The surface structure of claim 1 , wherein: the distance P between the centers of two neighboring protrusions is equivalent to a distance W between centers of two neighboring recesses formed between the protrusions. 6. The surface structure of claim 2 , wherein: a distance P between centers of two neighboring protrusions is equivalent to the distance W between the centers of two neighboring recesses.
