PROBLEM TO BE SOLVED: To provide an antenna device that easily solders an external conductor of an axial cable to a ground pattern portion.SOLUTION: The antenna device 10 for transmitting and receiving radio waves of a predetermined frequency band has: a coaxial cable 20 having a center conductor 22 and external conductor 21; and an antenna element 30. The antenna element 30 has: an antenna pattern portion 32; and ground pattern portion 34. Soldering 51 of the center conductor 22 of the coaxial cable 20 is carried out at a first soldering part 324 of the antenna pattern portion 32, and the soldering 52 of the external conductor 21 of the coaxial cable 20 is carried out at a second soldering part 344 of the ground pattern portion 34. The ground pattern portion 34 has a ground pattern aperture portion 34a for defining the second soldering part 344 adjacent to the second soldering part 344. The second soldering part 344 is sandwiched between the first soldering part 324 and ground pattern aperture portion 34a. |
