SURFACE STRUCTURE FOR ARTICLE

In the invention, an unevenness is formed on the surface of an article, and a fine unevenness that is finer than the unevenness is formed on a distal end of a convexity of the unevenness. The unevenness is of such a shape that when a person's finger touches the surface of the article, the per-u...

Beschreibung
Zusammenfassung:	In the invention, an unevenness is formed on the surface of an article, and a fine unevenness that is finer than the unevenness is formed on a distal end of a convexity of the unevenness. The unevenness is of such a shape that when a person's finger touches the surface of the article, the per-unit-area proportion of the surface area where the finger and article come into contact is in a range 35% to 90%. Preferably, the unevenness is of such a shape that the proportion of the surface area where the finger and article come into contact is in a range 45% to 80%. Las irregularidades se forman en la superficie de un artículo. En la parte superior de cada protuberancia de las irregularidades, finas irregularidades más finas que las irregularidades se forman. Las irregularidades se forman de manera que, en una unidad de área de la superficie del artículo tocado por un dedo humano, una proporción de un área de contacto entre el dedo y el artículo está en el intervalo de 35% a 90%. Es preferible formar las irregularidades de forma que la proporción de un área de contacto entre el dedo y el artículo está en el intervalo de 45% a 80%.
