An antenna is provided with an electrical power feeding unit (60) and first to fourth elements (10, 20, 30, 40). The first element is connected to a GND (62) of the electrical power feed unit and is disposed in the same plane as a GND (72) of a wireless circuit while being electrically separated from the GND of the wireless circuit. One end of the second element is connected to the first element and the other end is an open terminal, the second element being disposed in the same plane as the GND of the wireless circuit. One end of the third element is connected to an electrical power supply unit (64) of the electrical power feed unit, the third element being disposed substantially perpendicular to the first element in a region occupied by the first element under the one end to which the electrical power supply unit is connected. One end of the fourth element is connected to the other end of the third element and the other end is an open terminal, the fourth element being disposed substantially parallel to the first element and disposed substantially at a right angle to a line that joins the one end of the second element connected to the first element and the other end of the second element.
