When the receiving coil 32 as an antenna is placed just above a heating wire, the unidirectional magnetic filed acts on the receiving coil 32, the inductive electromotive force is generated on the receiving coil 32, and the gain of the receiver 30 becomes maximum. On the other hand, when the receiving coil 32 is placed on an intermediate position between the heating wires, the inductive electromotive force generated on the receiving coil 32 is remarkably small, and the gain of the receiver 30 becomes minimum. An embedding position of the heating wire can be specified by repeating these operations to know a place of the maximum gain of the receiver 30.
