PROBLEM TO BE SOLVED: To improve efficiency in design development, eliminating necessity of substantial redesign of an antenna device after a portable telephone or the like is mounted to an electronic apparatus. SOLUTION: This antenna device 1 includes: first-third antenna elements 2 to 4 separated in terms of DC; an RF connection terminal 5 connected to the first antenna element 2; a first power supply plus terminal 6 connected to the second antenna element 3 in terms of DC; a first power supply minus terminal 7 connected to the third antenna element 4 in terms of DC, and insulated from the first power supply plus terminal 6 in terms of DC; a plus terminal 8 for charging which is connected to the second antenna element 3 in terms of DC and the first power supply plus terminal 6 in terms of DC; and a minus terminal 9 for charging which is connected to the third antenna element 4 in terms of DC and the first power supply minus terminal 7 in terms of DC. The first antenna element 2, the second antenna element 3, the third antenna element 4, the RF connection terminal 5, the first power supply plus terminal 6, the first power supply minus terminal 7, the plus terminal 8 for charging, and the minus terminal 9 for charging are fixed by a fixing member 10.
