Abstract
A hair cutting member includes an optical waveguide, a connecting member, and a bonding member. The optical waveguide includes a core and a cladding that covers at least a portion of the core. The optical waveguide is disposed so as to emit light to hair growing on a skin. The connecting member retains an end of the optical waveguide. The bonding member bonds the optical waveguide and the connecting member to each other. The core is disposed off-center toward the outer circumference of the cladding. When viewed from an end face of the connecting member, a first distance between a center of the end face and an optical axis of the core is shorter than a second distance between the center of the end face and a center of the cladding. The technology of the present disclosure makes it possible to adjust the optical system of a hair cutting device easily.
