Antenna, antenna unit, and communication device using them

摘要

An antenna has a base substrate 3, a coil 30 formed from a conductor 4 wound around the base substrate 3, and a plurality of terminals 5 connected to the conductor 4. Uncovered base substrate portions 31 where the conductor is absent are formed on the base substrate 3 except the start and end of turns of the coil 30. The terminals 5 are provided on respective sides of the coil 30 parallel to a coil axis and on the uncovered base substrate portions 31.
