1. A non-contact power supply apparatus comprising:
- a first coil;
a second coil opposed to the first coil; and
a sensor including;
a plate-like insulator disposed between the first coil and the second coil;
a transmitting main antenna part formed, in a straight shape, on a first face of the insulator;
a transmitting sub antenna part formed on the first face of the insulator, intersecting the transmitting main antenna part, and electrically connected to the transmitting main antenna part;
a transmitting circuit electrically connected to the transmitting main antenna part, and transmitting a signal;
a receiving main antenna part formed, in a straight shape, on a second face, which is opposite the first face, of the insulator;
a receiving sub antenna part formed on the second face of the insulator, intersecting the receiving main antenna part, and electrically connected to the receiving main antenna part; and
a receiving circuit electrically connected to the receiving main antenna part,wherein the receiving circuit receives the signal through the receiving main antenna part and the receiving sub antenna part, and senses an object, except the insulator, between the first coil and the second coil, based on a change in a characteristic of the signal received.
