PROBLEM TO BE SOLVED: To improve reception performance by preventing the deterioration of a radiation characteristic when a connector is connected to a loop antenna which is formed on a film sheet to be stuck onto the upper part of a windshield in a vehicle. SOLUTION: Each antenna unit includes: the loop antenna 10 where two power feeding terminals 11, 12 are arranged in a linear antenna conductor part 23; the connector 20 having connection terminals 31, 32 to the two power feeding terminals 11, 12; and a coaxial cable 22 to be connected to the connector. After the connector 20 is connected to the loop antenna, the coaxial cable 22 is arranged along the linear antenna conductor part 23. The connection terminal 31 away from the coaxial cable 22 in the connector 20 is connected to the external conductor 22B of the coaxial cable inside the connector 20. The connection terminal 32 close to the coaxial cable 22 is connected to the center conductor 22A of the coaxial cable inside the connector 20. COPYRIGHT: (C)2008,JPO&INPIT
