ABSTRACT:
An antenna10aequipped on a mobile communication device1includes a helical antenna12protruding from a casing2(key side casing portion4) of the mobile communication device1and a cap13covering a surface of the helical antenna12and is constructed such that degradation of antenna gain of the helical antenna12due to contact of a finger100with the helical antenna is prevented by increasing a distance between an outer peripheral surface of the cap13and a surface of the helical antenna12to at least 1.00 mm by increasing a wall thickness of the cap13.
