Zusammenfassung:PROBLEM TO BE SOLVED: To provide an antenna coil capable of more improving a communication range. SOLUTION: A sealing part 17 covers an antenna substrate 11 and a magnetic core member 12 while the flat plate-shaped magnetic core member 12 is laminated in parallel with the antenna substrate 11 with an air core coil formed therein. The magnetic core member 12 is made of sintered ferrite. In this configuration, the antenna coil 10 excellent in a communication characteristic in a high frequency band can be obtained, and the sintered ferrite apt to be broken and insufficient in handleability can easily applied as the magnetic core member 12.
