摘要：
The present invention improves reception quality in an electronic apparatus including plural antenna devices. For this purpose, first antenna device (8) of electronic apparatus (7) according to the present invention includes ground organizer (10); feeding unit (11) placed on ground organizer (10); first antenna conductor (12) with its one end connected to feeding unit (11); and second antenna conductor (13) and third antenna conductor (14) both branch connected to the other end of first antenna conductor (12). The sum of the length of first antenna conductor (12) and that of second antenna conductor (13) is substantially (¼+n/2) times the wavelength of a signal in the first frequency band, and additionally the sum of the length of second antenna conductor (13) and that of third antenna conductor (14) is substantially (½+m/2) times the wavelength of a signal in the second frequency band.
