ABSTRACT:
A display unit includes a conductive portion1. When it is assumed that there is an imaginary straight line m1, which extends in a direction perpendicular to a longitudinal direction of a dipole antenna2, passes through a center of the dipole antenna2and is parallel to an antenna surface of the dipole antenna2, the dipole antenna2is disposed on a lateral side of the display unit so that the imaginary straight line m1is parallel to a display screen, is parallel to an upper side1aor a lower side1bof a main surface of the conductive portion and passes a lateral portion of the conductive portion1. When the dipole antenna has a length LAin the longitudinal direction thereof, when the conductive portion has a thickness T, and when a radio wave for communication with the external device has a wavelength λ0in the air, the formula of λ0≧LA≧T is established, a one side of the conductive portion has a greater length than the wavelength λ0, and a shortest distance d between each of peripheral portions of radiating conductors2aand2band a peripheral portion of the conductive portion ranges from (LA/10) to 6LA.
