The center line surface roughness Ra is measured by using a high precision surface roughness meter OO produced by XX manufacturing Co. Ltd. and a chart is drawn under the condition of cut-off value 0.08mm and OX, according to JIS B0601. A portion of measured length L is cut out from a film surface roughness curve to the direction of the center line. When the center line of the portion is expressed as an X axis, the vertical direction is expressed as a Y axis, and a roughness curve is expressed as Y = f (X), the value obtained from the following expression is Ra (μm).発音を聞く 例文帳に追加
