PROBLEM TO BE SOLVED: To provide a monofilament which has excellent weaving stability when processed, is excellent in dimensional stability required for continuous printing performance, and is suitable for obtaining a high mesh high modulus screen gauze. SOLUTION: The polyester monofilament for screen gauze satisfies the followings: the largest point strength of a raw filament before a thermal treatment is 5.0-7.0 cN/dtex; the strength at an elongation of 5% is 2.5-3.7 cN/dtex; the largest point elongation is 20-45%; wet heat shrinkage percent is 2.5-9.0%; the largest point strength of the raw filament after a wet heat treatment after woven is 5.0-6.5 cN/dtex; the strength at an elongation of 15% is 3.0-5.0 cN/dtex; the largest point elongation is 20-40%.
