Abstract: Provided is a method for manufacturing a fishing net formed from a plastic net that can be handled by winding or folding although the net has plastic rigidity. The fishing net is manufactured by (1) a step of preparing a multifilament yarn formed by bundling a plurality of core-sheath type composite filaments, in each of which a core component is made of polyethylene terephthalate and a sheath component is made of polyolefin, (2) a step of preparing a yarn thread obtained by paralleling a plurality of the multifilament yarns, (3) a step of twisting or braiding four yarn threads 11, 12, 13, 14 to obtain a net constructed with strands 1 and intersections 2, (4) a step of heat-treating the net under without pressure to melt the sheath component of the yarn threads 11, 12, 13, 14 constituting the strands 1 and the intersections 2, followed by solidifying, thus obtaining a plastic net, and (5) a step of forming the fishing net using the plastic net.
