A communication apparatus includes a touch panel for inputting a command by touching a surface thereof having an oblong profile short in one direction relative to the other direction orthogonal thereto, the touch panel outputting a touch position detection data in response to a touch given to a spot on the surface thereof for locating the touch position but not outputting touch position detection data when some other spot is touched while the spot is being touched, a speaker arranged outside and near one of the edges of the touch panel running in the one direction and a microphone arranged outside and near the other edge of the touch panel running in the one direction. The touch panel provides a command input region inputting a command in at least a part of the surface thereof arranged along the other direction and close to the other edge in a talk mode.
