PROBLEM TO BE SOLVED: To provide a thin antenna apparatus, in an antenna apparatus in which large power transmission and thinning are required.SOLUTION: An antenna apparatus 1, including a spiral coil 2, one or more magnetic layers 5 for supporting the spiral coil 2, and a circuit board 7, further includes a notch part 9 disposed from the inner peripheral side to the outer periphery of the spiral coil of the magnetic layer 5. In the notch part 9, there is installed the circuit board 7 having a terminal part 8 to connect to an extension line of the spiral coil 2 and a connection terminal 10 to connect to an external electric path. An extension line 3a on the inner peripheral side of the spiral coil is connected to a terminal part 8a on the inner peripheral side of the circuit board 7. Also, an extension line 3b on the outer peripheral side of the spiral coil is bonded to a terminal part 8b on the outer peripheral side of the circuit board 7. |
