<P>PROBLEM TO BE SOLVED: To solve the problem wherein a position can be measured only once by operation for inserting a sensor probe into a pipeline and pulling out the sensor probe from the pipeline since position measurement is performed only when inserting the sensor probe toward a target position from the inlet/outlet of the pipeline in a conventional pipeline position measurement method. Ž<P>SOLUTION: In the pipeline position measurement method, an operation processing section 4 measures the position of the pipeline 1, based on data 2a, 5a when the sensor probe 2 is inserted toward the target position 1b from the inlet/outlet 1a of the pipeline 1 and when the sensor probe 2 is pulled to the inlet/outlet 1a from the target position 1b.
