PROBLEM TO BE SOLVED: To provide a patch antenna exhibiting a high gain even when the antenna is downsized. SOLUTION: A side face conductor 15 connected to a ground conductor 14 is provided to a side face of the dielectric base plate 11 of a patch antenna 10 having a patch electrode 12 and the ground conductor 14 on the ceiling and bottom faces, respectively. Since the side face conductor 15 acts similarly like a virtual conductor 15a formed by extending the ground conductor 14 toward the outer circumference of the ground conductor 14 with respect to the patch electrode 12, the functional size of the ground conductor 14 can be enlarged without the need of increasing the size of the dielectric base plate 11.
