Zusammenfassung:Provided is a wireless module that is capable of improving isolation between two antennas. This wireless module includes a substrate, a ground pattern disposed on the substrate, a first antenna, a second antenna, and a base plate that is conductive. The first antenna is disposed between one end of the substrate and the ground pattern, and includes a grounding part and a first power feeding part, the grounding part is connected to the ground pattern, and the first power feeding part is fed with a first signal. The second antenna is disposed between the other end of the substrate and the ground pattern, and includes a second power feeding part fed with a second signal. The base plate includes a first opposed portion that faces the first antenna, a second opposed portion that faces the second antenna, and a third opposed portion that faces the ground pattern and is short-circuited to the ground pattern. The base plate also has, on the third opposed portion, a short-circuit point at which the base plate and the ground pattern are short-circuited to each other. The short-circuit point is disposed on the third opposed portion at a position nearer to the first opposed portion than to the second opposed portion.
