To assemble two kinds of antenna elements symmetrical with each other by only changing the direction of folding to bend an antenna portion and considerably reduce fabrication cost. A satellite signal receiving antenna apparatus of the invention is characterized in a satellite signal receiving antenna apparatus including a first metal plate as a grounding electrode, a second metal plate constituted by being arranged opposedly to the first metal plate and an antenna element arranged between the first metal plate and the second metal plate for receiving a circularly polarized radio wave. Each of the antenna elements comprises a metal line for receiving the radio wave and an attaching member made of a plastic for supporting the metal line. The attaching member includes an inserting hole inserted with a base end portion of the metal line folded to bend vertically and a metal line inserting groove for supporting at least a portion of an antenna portion extended in a horizontal direction of the metal line, and the metal line inserting groove is formed to correspond to either of the metal lines folded to bend symmetrically in a left and right direction.
