A wrist device, which is an antenna built-in portable device, includes an armor case including an opening at least on the front surface side, glass that closes the opening, a metal bezel attached to the front surface of the armor case and arranged around the glass, and an antenna arranged in a space on the inner side of the armor case. The antenna is a planar antenna, a maximum radiation direction of which is arranged to be directed toward the outer side of the bezel crossing the thickness direction of the armor case. The antenna is arranged in a position not overlapping the bezel in the maximum radiation direction of the antenna. At least a part of the antenna overlaps at least a part of the bezel in the thickness direction of the armor case.

A rotary switch permits the interrelation between the angle of rotation of a rotary switch knob and the angle of integral rotation of a rotor and a contact spring to be set as desired. A rotary switch knob and a rotor are respectively provided with a first gear and a second gear, and are linked together by these gears. The rotor carries a contact spring fixed thereto. When the ratio between the respective teeth numbers of the first and second gears is suitably set, the interrelation between the rotational angle of the rotary switch and that of the rotor and the integral contact spring can be set as desired.
