The ground pad 12 has two ground test terminals 121, the signal test terminal pad 11 is disposed between the two ground test terminals 121, and the ground pad 12 is electrically connected to a ground point of the antenna device. The outer contour of the ground pad 12 of the present embodiment is square, a circular groove 122 is formed inside the ground pad, two ground test terminals 121 protruding from the side edge are disposed on the side edge of the ground pad 12 close to the rf signal line 31, the groove 122 is communicated with the outside of the ground pad 12 through an opening 123, and the two ground test terminals 121 are respectively disposed at two ends of the opening 123. The signal test terminal pad 11 is disposed at a middle position of the opening portion 123 and between the two ground test terminals 121. The signal test terminal pads 11 and the two ground test terminals 121 have proper pitches, respectively.
