PROBLEM TO BE SOLVED: To provide a ceramic-like Sushi tray made of plastics, which not only looks high-grade like a real ceramic tray but is hardly stained as Sushi is floated from the tray because of the unevenness of the tray. SOLUTION: The unevenness of patterns 3 (whirling or circular)of a potter's wheel, peculiar to the pottery, is formed on the upper surface of the plastic tray 1 so that the tray looks high-grade like a real ceramic tray.
