1. A method of manufacturing FPCB, for forming a pattern on a base film in a roll-to-roll method, the method comprising: a step of preparing a base film;a step of preparing a printing roll a surface of which is provided with a printing roll pattern in a direction inclined with respect to a moving direction of the base film; anda step of forming a pattern that is inclined with respect to the moving direction of the base film by the printing roll pattern as the base film passes the printing roll. 2. The method according to claim 1, wherein at the step of preparing a base film, the base film on which a conductive material is applied is prepared, andthe step of forming a pattern comprises a step of forming a photosensitive pattern on the base film by the printing roll, and a step of irradiating light to the base film on which the photosensitive pattern is formed, thereby the inclined pattern being formed on the base film. 3. The method according to claim 1, wherein at the step of preparing a base film, the base film on which a conductive material and a photosensitive material are applied on is prepared, andat the step of preparing a printing roll, the printing roll which has a hollow unit provided with a light source is formed inside the printing roll and which has a shielding pattern that selectively shields light emitted from the light source is prepared, and a jig for light transmission divided into a transmission area that transmits light and a shielding area that shields light is prepared between the printing roll and the base film. 4. The method according to claim 3, wherein the printing roll comprises a main body of a light-transmitting material, and the shielding pattern is formed on a surface of the main body to selectively transmit light. 5. The method according to claim 1, wherein at the step of preparing a printing roll, the printing roll is provided in a pair such that at the step of forming a pattern, the pattern is formed on both surfaces of the base film. 6. The method according to claim 1, wherein at the step of preparing a printing roll, gaps between the printing roil patterns at a same phase of the printing roll are prepared to be different from one another. 7. The method according to claim 1, wherein the printing roll pattern is prepared in a plurality of printing roll patterns. 8. The method according to claim 7, wherein the plurality of printing roll patterns are prepared such that gaps between neighboring printing roll patterns are different from one another. 9. The method according to claim 1, wherein at the step of preparing a printing roll, the printing roll pattern is prepared to be bent at a predetermined area. 10. An apparatus of manufacturing FPCB comprising a printing roll configured to form a pattern on a base film to form the pattern in a roll-to-roll method, wherein the printing roll comprises a printing roll pattern provided in a direction inclined with respect to a moving direction of the base film to form the pattern. 11. The apparatus according to claim 10, wherein a conductive material is applied on the base film, and the printing roll is configured to apply a photosensitive material on the base film. 12. The apparatus according to claim 10, wherein a conductive material and a photosensitive material are applied on the base film, and the printing roll comprises a hollow unit in which a light source is provided, and comprises a shielding pattern that selectively shields light emitted from the light source, and comprises a jig for light transmission divided into a transmission area that transmits light and a shielding area that shields light between the printing roll and the base film, thereby the pattern being formed on the base film. 13. The apparatus according to claim 12, wherein the printing roll comprises a main body of a light transmitting material, and the shielding pattern is formed on a surface of the main body to selectively transmit light. 14. The apparatus according to claim 10, wherein the printing roll pattern is provided in the form of coil from one end to the other end of both ends of the printing roll. 15. The apparatus according to claim 10, wherein gaps between the printing roll patterns at a same phase of the printing roll are different from one another. 16. The apparatus according to claim 10, wherein the punting roll pattern is provided in a plurality of printing roll patterns. 17. The apparatus according to claim 16, wherein the plurality of printing roll patterns are prepared such that gaps between neighboring printing roll patterns are different from one another. 18. The apparatus according to claim 10, wherein the printing roll pattern is prepared bent in a predetermined area. 19. The apparatus according to claim 10, wherein the printing roll is provided in a pair such that the pattern is formed on both surfaces of the base film.
