摘要：
A timepiece with a radio function assures both a good appearance and antenna performance. The GPS wristwatch 1 has a movement 110 for displaying the time, a conductive external case 101 that houses the movement 110, a crystal 130 that is disposed on the face side of the external case 101 and covers the surface of the movement 110, a C-shaped conductive antenna electrode 112, an annular dielectric substrate 111, an GPS antenna 11 disposed between the movement 110 and the crystal 130, and a conductive, round solar panel support substrate 120 disposed between the movement 110 and GPS antenna 11. The outside diameter of the solar panel support substrate 120 is smaller than the inside diameter of the external case 101 on the plane where the solar panel support substrate 120 is disposed.
