PROBLEM TO BE SOLVED: To provide an inspection method of a pipe and an inspection device of a pipe capable of taking a tomogram of a pipe set up in a narrow space in a short time. SOLUTION: This inspection method of the pipe has a first step for scanning the pipe by translating a radiation source and a radiation detector arranged oppositely to the pipe; a second step for the radiation detector to detect radiation emitted from the radiation source, at each optional scanning distance interval; a third step for creating a transmission image of the pipe, based on a radiation dose detected by the radiation detector; and a fourth step for constructing a tomogram or stereoscopic image of the pipe, based on the transmission image, thus providing the inspection method of the pipe and the inspection device of the pipe capable of taking in a short time, the tomogram of the pipe set up in the narrow space.
