A polyethylene terephthalate monofilament obtained by spinning a polyethylene terephthalate chip having an intrinsic viscosity of 0.8 to 1.3, which gives a stress-strain curve exhibiting an elongation of less than 2.5% at an initial stress of 2.0 g/d, with an initial modulus value of 80 to 160 g/d, an elongation of 7.5% or less in a stress range of from 2.0 g/d to 9.0 g/d, and an elongation of at least 2.0% or more in a stress range of from 10.0 g/d to the point of break, is provided.
