PROBLEM TO BE SOLVED: To surely connect a feeding pin to a patch electrode so as to obtain a stable antenna impedance, using a simple method. SOLUTION: A bulging part 115, which is slightly larger in diameter than that of a through-hole 105 of an antenna 100, is provided near a head 113 of a pin part 111 of the feed pin 110. The bulged part 115 is applied by a pressure of a certain degree, to insert the head 113 into the hole 115 of the antenna 100 until the head 113 is connected to the patch electrode 103 formed on a dielectric board 101, and the vicinity of the head 113 of the pin 110 is ultimately soldered by a solder 300. In this state, the pin 110 will not be moved by a small force, so that the electrical connection of the electrode 103 to the pin 110 is assured in stable manner.
