PROBLEM TO BE SOLVED: To provide an array antenna, whose axial ratio can be enhanced and where a feeder for a distributor and a delay line or the like can easily be wired. SOLUTION: This array antenna, that is configured by arranging n×n sets of circularly polarized wave microstrip antenna elements 3 on a dielectric base, is formed such that when the circularly polarized wave microstrip antenna elements 3 are arranged and each element 3A is placed so as to be turned by 90 degrees about the axis of its front direction, the extracted direction of its feeder 6 is selected the same as the extracted direction of the feeder 6 of the circularly polarized wave microstrip antenna elements 3A, before it is turned and a position of a feeding point 7 of the turned circularly polarized wave microstrip antenna elements 3D is adjusted to attain alignment.
