PROBLEM TO BE SOLVED: To perform profiling inspection of a pipe inside surface simply and accurately by easy operation. SOLUTION: A linear rod-like profiling rod 101 provided rotatably with a profiling plate 107 is connected rotatably with a hinge part 103 to a bent reaction support rod 102 provided rotatably with a reaction force support plate 111. When inserting this profiling device 100 into a pipe 51, shifting a ring part 104 to the base end side of the rods 101, 102, to thereby narrow the base end side and expand the tip side, a profiling agent 60 applied onto the profiling plate 107 is allowed to adhere onto the inner surface 52, and a reaction force is supported on the inner surface 52 on the opposite side by the reaction force support plate 111. When the profiling agent 60 is hardened, the ring part 104 is separated from the base end side, and a torsional force is applied to the rods 101, 102, and the profiling agent 60 is removed from the inner surface 52 and taken out to the outside of the pipe 51, to thereby inspect a transferred form.
