To provide an optical radio communication equipment improving the safety when a semiconductor laser light source is used and remarkably mitigating the limitations of using places and using methods.

A transmitter 2 is provided with the light emitting part 4 provided with a semiconductor laser light source 12 to be the light emitting source of laser light LB and a spreading lens 13 spreading the laser light LA from the semiconductor laser light source 12 arranged on the inner location than the location of the opening part 11A of the body 11 within the body 11 forming the opening part 11A for outputting laser light LB. By this light emitting part 4, the spread laser light LB is outputted and this spread laser light LB is defined as laser light LC for transmission. By the spreading lens 13, the energy density of the laser light LA can be reduced and the influence that the laser light LC for transmission gives human's eyes can be reduced.
