CONSTITUTION:A key board section 1 is fitted to an outside of a casing 2 containing a portable telephone set main body and imbeded to a recessed party 6 of the casing 2. A connection wire 4 between the key board 1 and an internal circuit is wired to the internal circuit of the console 2 through a notch 3 provided to the casing 2.
