PURPOSE: A multiple-wavelength laser needle apparatus is provided, which can activate each semiconductor laser in a continuous mode or a pulse mode and irradiate a stable laser beam to an affected part or an acupoint. CONSTITUTION: A multiple-wavelength laser needle apparatus comprises: first constant current feed ports(251,254,257) which convert power into a first constant current and control the size of the first constant current; first semiconductor lasers(261,264,267) outputting a laser beam with a first wave length corresponding to the first constant current; first current compensation parts(271,274,277) which generate a first voltage signal corresponding to the output of the laser beam and provide the signal to the first constant current feed port; and light transmitters(281,282,283) transferring the laser beam with the first wave length.
