To prevent scald caused by hair removal with laser (1), to reduce time for hair-removing treatment (2) and to eliminate irregularity of hair removal in hair-removing treatment (3).

(1) This hair-removing equipment eliminates irregularity of hair removal by removing the hair by plane by scanning the hair in a transverse direction with a line laser beam. (2) By irradiating a hair-removing treatment part with intense pulse beams of solid state laser without using the waveguide of an optical fiber, etc., the hair-removing treatment can be accelerated. In the hair-removing equipment, a compact laser oscillator is mounted on a laser irradiation tip part for realizing intense laser pulse light. (3) The equipment irradiates the hair with laser beams by synchronizing a moving speed and a laser beam irradiation time with each other so as to irradiate the hair removing treatment part with the laser beam after changing an irradiating position so as to avoid fixing of the laser beam to a single place.
