PROBLEM TO BE SOLVED: To provide an antenna built-in type electronic timepiece capable of accurate positioning and secure holding, even if a GPS antenna installed inside the timepiece is formed into a ring-shape.SOLUTION: An antenna guide projection 112 is formed to project in a direction perpendicular to a surface of a bottom board 38. The antenna guide projections 112 are arranged at plural locations in a circumferential direction of the bottom board 38. A lower surface portion of the ring-shaped antenna body 40 has a hollow part configured to engage with each antenna guide projection 112. The antenna body 40 is mounted so that the hollow part and the antenna guide projection 112 engage with each other. |
