Abstract
A resin coating layer has a shape line that indicates the shape of a surface and is divided by virtual straight lines parallel to the X axis and setting an area of recessed sections that protrudes below the virtual straight lines and an area of protruding sections that protrudes above the virtual straight lines. A virtual straight line at a position at which the area totals for the area of recessed sections and the area of protruding sections are equal is defined as the average line for unevenness. Areas that protrude downwards from this average line for unevenness are defined as recessed sections and areas that protrude above this average line for unevenness are defined as protruding sections. The average area Sa for one recessed section is 4-120 μmand the number M of recessed sections between two points having a distance of 1 mm therebetween is 3-20.
