The invention relates to a position information transmission apparatus, a position information transmission method, and a moving object. The purpose of the present invention is to reduce the influence of an AC magnetic field for power transmission on the transmission of a position signal when non-contact power transmission is performed between a moving body and a ground device by magnetic field resonance coupling. A position information transmission device (6, 6 ') is provided on one of a ground-side device (2) and a moving body that performs non-contact power transmission by magnetic field resonance coupling with the ground-side device, and is provided with: an AC power generation circuit (61) that generates AC power; an AC magnetic field generation circuit (62) that generates an AC magnetic field as a position signal when AC power is applied; and a power inflow suppression unit that suppresses the inflow of induced electromotive force into the AC power generation circuit, said induced electromotive force being caused by an AC magnetic field emitted from the power transmission-side resonance circuit (43) for non-contact power transmission.
