Abstract
Official abstract text for this publication.
A wrist-worn electronic device includes an antenna that receives externally transmitted radio signals; a case of which at least part is made of a non-conductive material; an information display unit that is housed inside the case, is flat, and is made of a non-conductive material; a back cover that is attached to the case and is made of a conductive material; and a reception unit that is positioned and housed inside the case between the information display unit and the back cover, and processes a reception signal based on radio signals received by the antenna. The antenna has an antenna electrode that is disposed and formed as a line around the outside of the information display unit. The back cover is connected to the ground potential of the reception unit and reflects the radio signals.
