A first conduction part (12) coated with a conductive paint is formed on a back housing (1CAR) to be attached to one housing of a portable telephone unit at a position near a hinge mechanism (9) which connects the one housing to the other housing of the portable telephone unit. A GPS antenna is disposed on the hinge mechanism (9) side inside the other housing. The first conduction part (12) is in contact with a conductive connection terminal (21). A condenser element (22C) and a coil element (22L) are connected in parallel between the connection terminal (21) and a reference potential line (10G) of a first circuit board (10) disposed inside the aforementioned one housing.
