PROBLEM TO BE SOLVED: To provide a power supplier capable of stabilizing the operation state of an intra-subject introduction device successively moving inside a body cavity more than before. SOLUTION: The power supplier capable of supplying power required for driving respective parts of the intra-subject introduction device by applying a magnetic field from the outside to the intra-subject introduction device provided with a power receiving coil has: a coil for sending power arranged so that the magnetic field through a coil surface passes through the intra-subject introduction device outside the intra-subject introduction device; and one, two or more magnetic field reduction coils for generating another magnetic field for canceling a part of the magnetic field generated near the conductive line of the coil for sending the power.
