PROBLEM TO BE SOLVED: To provide an apparatus for photographing the interior of a pipe which reduces the influence due to fluctuations by running water, without decreasing the running water and which can photographs all the interior of the pipe without omission, in detail. SOLUTION: A mobile unit 2 installs a photographic apparatus 3 having a rotatable camera 31 and moves within a sewer pipe 1. The camera 31 rotates about the axis in parallel with the central axis in the travelling direction of the mobile unit 2 at a constant speed. The camera 31 is rotated by a motor 32. A signal 33a, representing the rotation angle of the camera 31 detected by a rotational angle detector 33, is supplied to a data processor 35. The processor 35 transmits an image signal 31b of the camera 31 to the processor 35, when the rotation angle of the camera 31 becomes a photographic angle. An inclination angle detector 34 is provided which detects the inclination angle of the photographing apparatus 3. Information on photographing time, image, camera rotation angle, and inclination angle is transmitted to an information processing device 4. The information processing device 4 accumulates and extracts the images and data (photographing time, camera rotation angle, and inclination angle), and creates a developed image.
