There is provided an apparatus for receiving nuclear magnetic resonance signals by applying high frequency energy to a living body placed in a static magnetic field. The distal end portion of the insertion section of the endoscope has a rigid distal end portion and a bendable portion. A housing portion for housing a high frequency coil is provided between the rigid distance portion and the bendable portion. This structure makes it possible to assemble the high frequency coil into the endoscope in a compact manner and can reduce a patient's burden when the insertion section is inserted in the body cavity of the patient.
