Zusammenfassung:	Provided is greaseproof paper that, when folded, shows little reduction in grease resistance at the folded portion. The greaseproof paper includes a paper base and a greaseproof layer provided on at least one surface of the paper base, wherein the greaseproof layer includes an ethylene-vinyl alcohol-vinyl ester copolymer (A) and a fatty acid derivative (B), contains 1 to 100 parts by mass of the component (B) per 100 parts by mass of the component (A), and is in an amount of 0.5 to 5.0 g/m 2 in terms of dry mass. In the greaseproof paper, the ethylene-vinyl alcohol-vinyl ester copolymer (A) has a content of ethylene units of 1 to 15 mol%, has a total content of vinyl alcohol units and vinyl ester units of 85 to 99 mol%, and has a degree of polymerization of 300 to 2000. In the greaseproof paper, the fatty acid derivative (B) is a fatty acid amide compound.
