PROBLEM TO BE SOLVED: To provide a coil unit for antennas which can remove a stress generated in a packaging terminal due to the thermal expansion or thermal shrinkage of a rear window. SOLUTION: A coil unit 10 for antennas consists of a winding coil 16 in which a conductor wire is wound, a magnetic core 17 which is inserted and arranged in the interior of the winding coil 16, a conductive connector terminal 13 to which one end of the winding coil 16 is connected, a packaging terminal 14 to which another end of the winding coil 16 is connected having a first and a second packaging surface and a main body 14c and a resin member to which the packaging terminal 14 and the connector terminal 13 are attached and which has a mounting side to mount the winding coil 16. The coil unit 10 for antennas forms a first main body 14a and a second main body 14b which are divided from the main body 14c of the packaging terminal 14 as a buffering member to buffer the stress applied on the packaging terminal 14.
