A catheter using an optical fiber and a camera, the catheter comprising: a shaft formed therein with a hollow part lengthwise along the shaft, including a flexible material, and having a cylindrical shape; a cap including a head part having a same external diameter as an external diameter of the shaft, an inserting part integrally coupled to a side of the head part and having an external diameter identical to an internal diameter of the shaft such that the inserting part is inserted into an inner circumference of the shaft, a camera inserting groove having a cross sectional shape of U from an end of the head part to an end of the inserting part such that the camera inserting groove is concaved toward a center of the inserting part, and having a depth corresponding to 1/2 to 2/3 based on a diameter of the inserting part, a wire inserting hole transversely and straightly formed through the center of the inserting part while being spaced apart from an end of the head part, and having both ends to communicate with an outer circumference of the inserting part and an inner part to communicate with the camera inserting groove, a wire guide groove having a concave shape formed from both ends of the wire inserting hole to an end of the inserting part, and a lighting inserting groove and an injecting tube inserting groove which are spaced apart from each other and having a cross sectional shape of U from an end of the head part to the end of the inserting part; a wire having an insertion part to pass through the wire inserting hole and a longitudinal part formed along the wire guide groove while being coupled to the insertion part and having an outer circumference in contact with or spaced apart from the inner circumference of the shaft; a camera inserted into the camera inserting groove in such a manner that one end of the camera is aligned in line with the end of the head part and an opposite end of the camera does not reach the wire inserting hole, in which one side of an outer circumference of the camera makes contact with an inner surface of a center part of the camera inserting groove; a camera cable coupled to the camera and having a diameter smaller than a diameter of the camera to form a wire installation space between an inner surface of the camera inserting groove and the camera cable; an optical fiber having one side inserted into the lighting inserting groove and an opposite side installed along the hollow part in the shaft; a drug injecting tube having one side inserted into the injecting tube inserting groove and an opposite side installed along the hollow part in the shaft; a case to which an opposite end of the shaft is coupled; and a driving device installed in the case and connected to the wire to pull or release the wire to rotate a front end of the shaft and the cap inserted into the front end of the shaft. a shaft formed therein with a hollow part lengthwise along the shaft, including a flexible material, and having a cylindrical shape;
