The position information transmission device (6, 6') is provided at one of a ground side apparatus (2) and a moving object (3) performing non-contact power transmission by magnetic field resonance coupling with the ground side apparatus, and includes an alternating current power generation circuit (61) for generating alternating current power, an alternating current magnetic field generation circuit (62) for generating an alternating current magnetic field as a position signal when the alternating current power is applied; and a power inflow suppression part (65, 66) for keeping induced electromotive force due to an alternating current magnetic field generated from a power transmission side resonance circuit (43) for the non-contact power transmission from flowing to the alternating current power generation circuit.
