PROBLEM TO BE SOLVED: To prevent antenna characteristics from being deteriorated by a human body in an antenna system installed in a case. SOLUTION: The antenna system comprises: an antenna (12) to be installed in a first case unit (6); a parasitic element (14) provided in a second case unit (8) coupled to the first case unit for obtaining an antenna function through capacitive coupling with the antenna; and a conductor (printed circuit board 36) installed in the second case unit (8) for suppressing radiation from the parasitic element (14) to one side of the second case unit (8).
