Summary:PURPOSE:To facilitate the irradiation of an even light distribution of laser light to the surface of skin in the optimum condition by providing a handpiece with a guide bar whose end face is made flat while a position thereof matches a focal plane of the laser light. CONSTITUTION:A guide bar 17 strong with a proper size is made to stick output along an axis line of a handpiece body 10a at such a position that disturbes no treating irradiation field keeping the handpiece 10 vertical to an optical axis of an outgoing laser light from a tip end 10b of the handpiece 10 to a surface corresponding to a focusing position thereof. Length to the tip end face 17a of the guide bar 17 from a lens 3 is made equal to a distance to a point on which an image with the lens 3 focuses. To match a vertical plane to the laser optical axis with ease, the tip end face 17a of the guide bar 17 is made flat to coincide with the vertical plane thereto. In treatment, the handpiece 10a is held to make the tip end face 17a of the guide bar 17 sticking out from the tip 10b thereof abut skin.
