A method for manufacturing a fuel tank using a polyketone, according to the present invention, comprises: a cover injection-molding step for injection-molding an upper cover and a lower cover through an injection-molding machine; a cover assembly step for disposing the upper and lower covers, which have been injection-molded through the cover injection-molding step, at upper and lower positions, respectively, and then assembling the same; and a cover welding step for welding the contact surfaces of the upper and lower covers, which have been assembled in the cover assembly step, with a laser. Accordingly, the present invention may provide a fuel tank made of a polyketone and a manufacturing method therefor, in which a pair of upper and lower covers are simultaneously molded and extracted, assembled through a machine, and then directly welded to each other, whereby it is possible to achieve automation, mass-production, and a marked reduction in cost, and necessary rigidity is satisfied by only the rigidity of a polyketone material without any separate reinforcing object, whereby it is possible to achieve weight reduction of a fuel tank.
