Abstract: A patch antenna can prevent a feed point (solder) from rising upward beyond the main surface of an antenna radiation electrode, and a method of making that patch antenna. A dielectric base plate (12A) has, on its top surface (12u) side, a recess (12c) that is provided in the periphery of a base plate through-hole (12a). This recess (12c) is able to accommodate a head (181) of a feed pin (18) and solder (15A), and also has a depth that is greater than the height of the head (181) of the feed pin (18). The antenna radiation electrode (14A) is formed on inner wall surfaces (12c-1) defining the recess (12c). In a state in which the head (181) of the feed pin (18) is accommodated in the recess (12c), solder (15A) is placed not to project upward beyond the main surface of the antenna radiation electrode (14A).
