An endoscope inserted-shape detecting apparatus 8 includes a sense coil unit 23 in which multiple sense coil groups of sense coil groups 23 A to 23 I for detecting magnetic fields generated by multiple source coils 21 in an inserted-shape detecting probe 6 are placed as a part of the endoscope inserted-shape detecting apparatus 8 , a signal detecting section 33 , a source coil position analyzing section 35 and a signal control section 37 that selects a magnetic-field detecting element to be used for detection of a magnetic field signal based on the magnetic field generated by each of the source coils 21 from the sense coil groups 23 A to 231 I in a control section based on positional information signals outputted from the source coil position analyzing section 35.
