PURPOSE: To provide an arm mounted communication equipment taking an actual use form into consideration. CONSTITUTION: Uncoated arm holders 2, 3 are attached to both sides of a communication equipment body 1 as a mounter, respectively. Flat-shaped chip antennas 4, 5 are arranged in the arm holders 2, 3, respectively. When the communication equipment body 1 is mounted to an arm, the chip antennas 4, 5 are positioned on a radius side 6 and an ulna side 7 of an arm, and the arm mounted communication equipment transmits and received electric waves. When communication equipment body 1 is detached from an arm and is used by holding it to an ear, the electric waves are transmitted and received so as to avoid a ground effect of the human body. The chip antennas 4, 5 are structured by a ground pattern on an antenna base plate, a dielectric arranged in the upper part, and further a conductor foil which is called a patch pattern provided on the above surface.
