PROBLEM TO BE SOLVED: To provide a desk mat composed of a non-chlorine-based resin which eliminates the tendency to curl developed through being kept in a winding state for a long period and has excellent recovery properties of the trace of writing. SOLUTION: The mat is obtained by adding 5 to 50 pts.wt of at least one type of ester (A component) as a plasticizer selected from an aromatic hydroxy carboxylic acid, a hydroxy condensed polycyclic aromatic carboxylic acid, a hydroxy alicyclic carboxylic acid, or an anhydride of these carboxylic acids or a lower alkyl ester, and at least one type of ester (B component) selected from a hydroxy compound selected from an aliphatic alcohol, an alicyclic alcohol, an aromatic alcohol, a phenol and an alkylphenol or from an alkylene oxide adduct of these hydroxy compounds, to 100 pts.wt. of an amorphous random copolyester resin, which contains 80 mol% of repeating units comprising an 8 to 14C aromatic dicarboxilic acid and has a glass transition point of 40 to 150°C, to form a mat main body, forming a protective layer on one surface or both surfaces thereof.
