摘要

PROBLEM TO BE SOLVED: To provide a built-in antenna portable device capable of improving a quality and preventing deterioration of reception performance.SOLUTION: A wrist wearable device 1 which is an antenna built-in portable device includes: an exterior case having an opening at least on a surface side; a glass 13 that covers an opening; a metal bezel 16 fitted to the surface of an exterior case 2 and arranged around the glass 13; and an antenna 30 arranged in a space inside the exterior case 2. The antenna 30 is a planar antenna whose maximum radiation direction R1 crosses a thickness direction A1 of the exterior case 2 and which is arranged in the direction toward the outside of the bezel 16. The antenna 30 is arranged at a position not overlapped with the maximum radiation direction R1 of the antenna 30 with respect to the bezel 16. At least a part of the antenna 30 overlaps with at least a portion of the bezel 16 in a thickness direction A1 of the exterior case 2.
