PROBLEM TO BE SOLVED: To provide a switch and communication apparatus for which a conduction by contact of a pin is not used. SOLUTION: A switch 100 has a mobile conductor unit 120 which is conducted with a circuit and connected with an external antenna when the external antenna is connected to a communication apparatus. A surface of a substrate 300 has a conduction area 302 conducted with an external antenna. The mobile conductor unit 120 is moved with movement of the external antenna and, when the external antenna is not connected, is located at a first position in contact with the conduction area 302 to be conducted with the internal antenna but, when the external antenna is connected, is located at a second position separated from the conduction area 302 to be insulated from the internal antenna.
