PROBLEM TO BE SOLVED: To provide an electronic device in which communication efficiency is improved and a sufficient antenna gain can be obtained. SOLUTION: A display unit includes a conductive portion 1. When it is assumed that there is an imaginary straight line m<SB>1</SB>, which extends in a direction perpendicular to the longitudinal direction of a dipole antenna 2 passes through the center of the dipole antenna 2 and is parallel to the antenna surface of the dipole antenna 2, the dipole antenna 2 is disposed on the lateral side of a display unit so that the imaginary straight line m<SB>1</SB>is parallel to a display screen 4a, parallel to the upper side 1a or the lower side 1b of the main surface of the conductive portion 1 and passes a lateral portion of the conductive portion 1. When the dipole antenna 2 has a length L<SB>A</SB>in the longitudinal direction thereof, when the conductive portion has a thickness T and when a radio wave has a wavelengthλ<SB>0</SB>in the air, the formula ofλ<SB>0</SB>≥L<SB>A</SB>≥T is established, one side of the conductive portion 1 has a longer length than the wavelengthλ<SB>0</SB>and a shortest distance (d) between each of peripheral portions of radiating conductors 2a and 2b and a peripheral portion of the conductive portion 1 ranges from (L<SB>A</SB>/10) to 6L<SB>A</SB>.
