PROBLEM TO BE SOLVED: To provide a casing of a wireless communication product with a common antenna. SOLUTION: An antenna conductor circuit 2 selected in advance is integrally cast inside a casing 1. The antenna conductor circuit 2 is formed with a feed end 21 consisting of a plug needle or spring strip in advance. By being combined with a circuit board inside a product, the feed end 21 forms electrical coupling with the circuit board. The antenna conductor circuit 2 is integrally cast on the front surface, inside, or on the inner surface of the casing 1, and gives a distribution shape of a flat plane, curved plane, or multilayer solid by being combined with the unspecified shape of the casing 1. An antenna is so arranged as to be separated from the circuit board 1 and be dependent on the casing 1. Due to this structure, the circuit board space can be kept clean and the volume of an antenna module can be reduced, resulting in leading to the reduction in volume of the wireless communication product.
