Abstract
A method for forming a resin surface on which recessed portions different in size are formed randomly includes: forming first recessed portions by allowing all or some granular and/or powdery adhering material to adhere to a surface of an unset resin composition containing air bubbles so that at least a portion of the granular and/or powdery adhering material bites into the surface and by removing the adhering material after the resin composition is set; and forming second recessed portions smaller than the first recessed portions in size by allowing some of the air bubbles contained in the unset or set resin composition to open on the aforementioned surface of the resin composition.
