Providing a kind of endoscope insertion shape analyzing system includes insert state acquiring unit, for obtaining the multiple portions of coordinate value, it is inserted into endoscope main body in the portion, it is embedded in shape detecting unit, for detecting the object of at least part of insertion portion of inserted-shape, according to the multiple portions of the coordinate value. The coordinate plane setting unit for further comprising is arranged multiple coordinate planes and is respectively inserted into multiple coordinate planes according to the multiple portions of coordinate value and the shape of insertion and inserted-shape projecting unit projection of shape. Including be more a kind of inserted-shape determination unit with the presence or absence of the inserted-shape on regulation shape project to the multiple coordinate plane each side.
