Provided are a printing paper which is made of an aliphatic polyester resin making use of a biomass raw material derived from plant resources, is excellent in running stability on a printer, substrate strength, halftone dot reproducibility, printing sharpness and water resistance and is suited for use in sheetfed offset printing, for example, commercial printing of outside posters, maps, catalogues, brochures and menus; and a label using the printing paper. The printing paper is made of an aliphatic polyester resin composition comprising from 40 to 90 wt.% of (a) an aliphatic polyester resin having at least an aliphatic diol unit represented by the following formula (I) and an aliphatic dicarboxylic acid unit represented by the following formula (II); and from 60 to 10 wt.% of (b) fine inorganic powders; and has a Gurley stiffness of from 50 to 3,000 mg, a surface area S of from 5,000 to 50,000 µm 2 per 4,292 µm 2 of a projected area on the surface of the printing paper, and a volume V, at a convex portion on the surface of the printing paper, of from 2,000 to 20,000 µm 3 per 4,292 µm 2 of a projected area on the surface of the printing paper.
