PROBLEM TO BE SOLVED: To provide an array antenna provided with desired directivity wherein antenna elements are efficiently arranged and formed. SOLUTION: Antenna elements 2a to 2t are linearly arranged and formed on the surface of a board 1 respectively at a prescribed interval, the arrangement direction of which is a long side direction of the board 1. Further, a phase inverting distributor 6 is formed at a position corresponding to each position between the antenna elements 2i, 2j on the surface of the board 1, and master feeder lines 4 are formed, which are extended along the arrangement directions from the phase inverting distributor 6. Each of the antenna elements 2a to 2t and the master feeder lines 4 are connected by slave feeder lines 3a to 3t each having a desired impedance, and the slave feeder lines 3a to 3t are respectively connected to the antenna elements 2a to 2t nearly in the middle of sides perpendicular to the arrangement directions of the phase inverting distributor 6 at the antenna elements 2a to 2t.
