In this case, when printing or etching is used in forming the antenna member, the antenna member can be easily formed on the printed circuit board, which is effective in reducing costs.

A thin portion is formed in the second case, and the printed circuit board and the metal are formed. When the frame and the metal cover are housed in the first and second cases, the antenna member and the thin portion are opposed to each other, and when the inside of the first and second cases is sealed, the antenna passes through the thin portion. The antenna member can receive satellite radio waves, improve the receiving sensitivity of the antenna member, and prevent foreign substances such as dust and water droplets from entering the first and second cases. The antenna member can receive the satellite radio wave stably and accurately without receiving.
