A meshed plastic filter of a narrow-pitch net with a net structure and a frame structure formed in either a square or a circular overall shape into a plastic injection molded unitary body includes a dam/discharge rib in the net structure for storing molten plastic material and accumulating pressure of the molten plastic material, thereby enabling implementations of a fine-pitch net filter having mesh holes of 0.2 mm in diameter at a spacing of 0.3 mm, which has diverse applications, such as a filter or sieve for gasoline or oil, a dust collector filter and other various filtration.
