Title:
ELECTRONIC WATCH
Document Type and Number:
Japanese Patent JP2022176758
Kind Code:
A
Abstract:
To provide an electronic watch that can certainly fix a movement and can prevent a reduction in reception performance.SOLUTION: An electronic watch comprises: an antenna that includes an annular substrate and an antenna element and receives a radio wave; a circuit board that includes a receiving unit for processing the radio wave received by the antenna, a power feeding terminal for feeding power to the antenna, and a ground terminal; a power feeding member that establishes conduction between the antenna element and the power feeding terminal; a conductor plate 160 that is arranged between the antenna and the circuit board in lateral view seen from a direction orthogonal to a central axis of the antenna; and a first fixing member 180A and second fixing members 180B that fix the conductor plate and the circuit board to each other. The first fixing member is arranged at a position closer to the power feeding member than the second fixing members in plan view seen from a direction of the central axis and fixes the conductor plate and the ground terminal in a conduction state, and the second fixing members fix the conductor plate and the ground terminal in an insulation state.SELECTED DRAWING: Figure 7
