A1

An antenna includes a plurality of antenna elements that transmit and receive radio waves in a plurality of frequency bands, and enables downsizing while the influence which the directivity or the like in the transmission and reception of radio waves in some frequency band receives from an antenna element that transmits and receives at a frequency higher than frequencies within the frequency band is curbed. An antenna unit (110) that constitutes the antenna is provided with a low-frequency antenna that is provided on the surface of a low-frequency reflecting plate (150) and transmits and receives radio waves in a low-frequency band, and a high-frequency antenna that transmits and receives radio waves in a high-frequency band, and is further provided with conductors that are respectively provided toward the reflecting plate from two element parts of the high-frequency antenna, the distance therebetween in a direction parallel to the low-frequency reflecting plate (150) being longer on the side close to the low-frequency reflecting plate (150) than the side far therefrom.
