To provide a radio communication mobile station of simple constitution which enables a natural-attitude radio communication for a radio communication system which uses an opto-radio wave as a transmission medium from a radio communication mobile station to a radio communication base station.
The radio communication mobile station has a body part 1 which has the device of the station inside and can be gripped and a light emission part 2 which emits an opto-radio wave, and the light emission part is coupled with the body part while the angle of its bottom surface to the length axis of the body part is so determined that a light reception part 3 of the radio communication base station and the light emission part 2 of the radio communication mobile station face each other and the opto-radio wave is emitted.
