Zusammenfassung:	A communication apparatus electrically connected to a first antenna through a first cable includes a second antenna that is substitutable for the first antenna; a first ground portion to which a second cable for grounding the first antenna is connected; an antenna detection circuit to detect a state of the first antenna; an antenna switching unit to switch from the first antenna to the second antenna, in a case where the antenna detection circuit detects an abnormality of the first antenna; and an insulating portion to insulate the first ground portion from a second ground portion around the first ground portion, in a case where the antenna detection circuit detects an abnormality of the first antenna.
