<P>PROBLEM TO BE SOLVED: To prevent a deterioration in the reception sensitivity of a built-in antenna to facilitate its size reduction. <P>SOLUTION: This wrist watch with a radio function is equipped with the antenna comprising an antenna coil and used to receive a prescribed electric wave, and a circuit board 50 with a processing circuit formed thereon to perform various processes based on the received electric wave. The antenna and the circuit board 50 are disposed so that their respective orthogonal projections onto a plane vertical to the thickness direction of the wrist watch overlap with each other. The processing circuit is equipped with a mounted component and a pattern P for wiring while only the pattern P is disposed in an area CA of an orthogonal projection of the antenna coil onto the plane. <P>COPYRIGHT: (C)2008,JPO&INPIT |
