PROBLEM TO BE SOLVED: To provide an antenna device capable of highly efficiently light-emitting in comparison with a conventional one.SOLUTION: In an antenna device, an outer case is formed by a light block body 16 and a light transmission body 17. A metallic capacitance element 3 is positioned in the vicinity of the upper end in the outer case. At least a part of a planar part 3a of the capacitance element 3 is opposite to the light transmission body 17. An LED 20a of a light-emitting module 18 is positioned on the side of the capacitance element 3. Light emitted by the LED 20a is led to the light transmission body 17 by a light guide body 19. The planar part 3a of the capacitance element 3 is positioned on the side opposite to the light transmission body 17 to be functioned as a reflector while sandwiching the light guide body 19.SELECTED DRAWING: Figure 9 |
