Abstract: There is provided an antenna that enables easy soldering of an external conductor of a coaxial cable to a ground pattern. An antenna device 10 capable of transmitting and receiving a radio wave includes a coaxial cable 20 having a center conductor 22 and an external conductor 21 and an antenna element 30. The antenna element 30 has an antenna pattern 32 and a ground pattern 34. The center conductor 22 is soldered to a first solder portion 324 of the antenna pattern 32, and the external conductor 21 is soldered to a second solder portion 344 of the ground pattern 34 by means of solder 52. The ground pattern 34 has an opening 34a defining the second solder portion 344. The second solder portion 344 is provided between the first solder portion 324 and the opening 34a.
