PROBLEM TO BE SOLVED: To simplify a structure, to improve productivity and to ensure a mechanical strength suited to installation while realizing a sufficient omnidirectional property on a horizontal surface. SOLUTION: The horizontal polarization omnidirectional array antenna comprises: an antenna substrate 1 whereon a pair of parallel power feeding lines 5, 5 are formed on front and back surfaces of a terminal portion along with a long side of a rectangular plate which is supported vertically; a plurality of dipole antennas 6 which are connected and arrayed along with the pair of power feeding lines 5, 5; and a balanced/unbalanced conversion section 2 that is formed on a proximal portion of the antenna substrate 1 for allowing the pair of power feeding lines 5, 5 to serially feed power.
