PROBLEM TO BE SOLVED: To improve depilation effects by efficiently burning entire hair follicles by simultaneously irradiating hair follicle tissues on the surface of skin with light from multiple directions by splitting light emitted in a single direction into luminous fluxes of plural directions through optical equipment and converging respective luminous fluxes from another angle to one point through optical equipment later. SOLUTION: The luminous of laser light emitted in the single direction is temporarily split into luminous fluxes of plural directions by plural pieces of optical equipment 1-3 composed of prism, mirror, beam splitter and glass fiber, for example, and respective luminous fluxes are converged from the other angle to one point later. Namely, in the case of treating hair growing where it is not wanted, the hair follicle tissue at the relevant spot is simultaneously irradiated with light from multiple directions and the entire hair follicle is burnt. Namely, the problem of not burning the portion to become a shadow of a hair shaft (a) not to be irradiated with light like a conventional example of irradiating the hair follicle with light in the single direction is canceled. Thus, the entire hair follicles are efficiently burnt and the depilation effects are improved.
