Abstract: A rectangular spiral-shaped coil conductor (CW) is formed on a flexible substrate (10). A rectangular aperture is made in the central portion of the area where the coil conductor (CW) is formed, and a magnetic core (1) is disposed in the aperture. The coil conductor (CW) includes a first conductor portion (11) adjacent to a first main surface (MS1) of the magnetic core (1) and a second conductor portion (12) adjacent to a second main surface (MS2) thereof. The magnetic core (1) and the coil conductor (CW) form an antenna coil (21). A circuit substrate (20) includes a ground electrode formation area (GA) and a ground electrode non-formation area (NGA). The antenna coil (21) is mounted on the ground electrode non-formation area (NGA) of the circuit substrate (20) with the first main surface (MS1) of the magnetic core (1) facing the circuit substrate (20).

Abstract: An antenna apparatus (101) includes a power supply coil (8), a booster electrode sheet (7), a magnetic sheet (6), and a ground substrate (5) in this order from the top. The power supply coil (8) is obtained by forming a spiral coil conductor (81) on a flexible substrate (80). The booster electrode sheet (7) is obtained by forming a booster electrode (71) on an insulating substrate (70). The booster electrode (71) includes a conductor region covering the coil conductor (81), a conductor aperture (CA) covering a coil window (CW), and a slit portion (SL1) connecting the outer edge of the conductor region and the conductor aperture (CA) in plan view. The magnetic sheet (6) covers the booster electrode sheet (7) so that the magnetic sheet (6) covers a region slightly larger than a region including the conductor aperture (CA) and the slit portion (SL1) of the booster electrode (71).
