Abstract
A hair cutting device according to the present disclosure comprises an optical waveguide. The optical waveguide comprises a light irradiator. The light irradiator irradiates hair protruding from the skin with light to cut the hair. The refractive index of the light irradiator is smaller than the refractive index of the surface of the skin. As a result, options such as the material of the optical waveguide and the like can be increased. Furthermore, for example, when the skin is appropriately irradiated with light from the light irradiator, an action on the skin such as sterilization or activation can also be expected.
