PROBLEM TO BE SOLVED: To provide a polyester fiber knitted fabric, in which dispersion of the elongation is reduced as much as possible, suitably useable for applications such as materials of construction and industrial materials by constituting the knitted fabric of a polyester fiber in an extremely slight generation amount of materials attached to a spinneret even when spinning is continuously carried out through the spinneret for a long time. SOLUTION: The knitted fabric is constituted of the polyester fiber composed of a polyester polymer polymerized by using a deposited material obtained by heating a specific titanium compound and a specific phosphorus compound in a glycol as a catalyst.
