The objective of the present invention is to provide an X-ray grid fabric capable of significantly improving the clarity of images by using synthetic resins of which the penetration ratio is hugely different from lead, as intermediate materials. The present invention comprises: a lead foil (100), a thin board; and a synthetic resins layer (200) coated on one side of the lead foil (100) and fixated on the same. Additionally, the manufacturing method comprises: a lead foil providing step of providing lead foils (100) continuously; a polyester sheet providing step of providing polyester sheets (300) continuously to the upper surface of the lead foil (100); an ultraviolet ray hardening solution spraying step of spraying an ultraviolet ray hardening solution (210) on the lower surface of the polyester sheet (300); a pressing roller processing step of processing a pressing roller (11) for pressing the polyester sheet (300) and lead foil (100) on which the ultraviolet ray hardening solution (210) is coated; an ultraviolet ray irradiation step of irradiating ultraviolet rays from an ultraviolet ray lamp (22) on the ultraviolet ray hardening solution (210) pressed between the polyester sheet (300) and lead foil (100) as passed through the pressing roller (11), thereby hardening the ultraviolet ray hardening solution (210) and fixating the same on the lead foil (100); and a polyester sheet separating step of separating the polyester sheet (300). |
