A magnetic field generating apparatus 20 is the magnetic field generating apparatus 20 that transmits a control signal by a magnetic field to a capsule endoscope 10 that performs control of start and stop according to the control signal. The magnetic field generating apparatus 20 includes a housing 25 including a storing section 21 in which the capsule endoscope 10 is arranged, a magnetic field generating section 42 that generates the magnetic field, and a shield section 26 that shields a leakage electromagnetic field leaking to an area other than the storing section 21 in the magnetic field generated by the magnetic field generating section 42.
