PROBLEM TO BE SOLVED: To provide a small and inexpensive indirectional polarization diversity antenna. SOLUTION: An antenna element for vertical polarization, an antenna element for horizontal polarization, and a polarization switching section arranged to output a signal received by the antenna element for vertical polarization or a signal received by the antenna element for horizontal polarization selectively are arranged in the axial direction. A feeder line led out from the antenna element for vertical polarization is arranged to pass through the central portion of a region formed by the antenna element for horizontal polarization.
