Provided is a disposable endoscope that enables simple treatment by capturing an image inside a body as a moving picture or photo, and in particular, that enables replacement of a probe portion inserted into the body and that preemptively prevents infection in patients due to repeated usage. The disposable endoscope includes: a main body that is connected to a monitor, and in front of which a light emitting portion and a light receiving portion are arranged in parallel a light emitting fiber that guides light from the light emitting portion toward an object to be examined a light receiving fiber that guides light reflected from the object to be examined toward the light receiving portion and a light adjustment unit that is placed within the protective tube that is adjacent to ends of the light emitting fiber and the light receiving fiber and that adjusts a position of light toward the object to be examined or light reflected from the object to be examined, wherein the light receiving fiber guides light that is reflected from the object to be examined through the light adjustment unit toward the light receiving portion. A probe portion inserted into a body of a patient or a user is used only once so that cross-contamination caused by repeated usage can be prevented in advance. A structure of the disposable endoscope is simple so that costs can be reduced due to reduction in a unit cost of production. A portion in which photographing of a moving picture or photo is substantially performed can be precisely controlled so that a precise diagnosis can be carried out. Photographing of a moving picture or photo with high resolution can be performed using a plurality of mirrors and lenses so that the quality of a patients treatment or therapy can be improved.
