The present invention relates to a method for manufacturing an X-ray grid using a continuous pressurizing method, which can precisely form a tilt angle of each X-ray absorbing material by continuously piling up multiple adhesive sheets through high-temperature pressurization and cooling pressurization to realize a high precision and a high quality and to improve productivity through mass-production. The method of the present invention comprises: a step of forming an adhesive sheet to attach an X-ray penetrating material and an X-ray absorbing material in the form of a sheet having a continuous length with a mutual hot melt adhesive and to form the adhesive sheet a step of forming a cutting sheet to cut the adhesive sheet into a certain length and to form multiple cutting sheets a step of piling up the cutting sheets to consecutively piling up the cutting sheets in a jig unit whose internal floor, where the cutting sheets are settled, is inclined toward one side at a certain angle a step of forming a grid block to pressurize with a high temperature the top surface of each of the cutting sheets piled up by the step of piling up the cutting sheets with a heating pressurizing surface of a heating pressurizing pusher, to melt the hot melt adhesive, to make each of the cutting sheets consecutively piled up and inclined at a certain angle receive a continuous pressurizing means while hardening the hot melt adhesive by performing cooling pressurization with a cooling pressurizing surface of a cooling pressurization pusher, and to form it into a grid block in the shape of a trapezoid with the top surface and the bottom surface tapered and, a step of forming the main frame of a grid to slice the grid block along the direction of piling up vertically into a certain thickness and to form the main frame of the grid in the shape of a plate.COPYRIGHT KIPO 2016본 발명은 복수의 접착시트를 연속적으로 고온가압 및 냉각가압 적층하면서 각각의 X선흡수물질의 경사각도를 정밀하게 형성할 수 있어 보다 고정밀 및 고품질을 실현하면서도 대량생산을 통한 생산성을 향상시킬 수 있는 연속가압방식
