1. A hair cutting member comprising:
a light emitting module including
an optical waveguide extending in a first direction and including a core and a cladding covering at least a portion of the core, and
a retaining member retaining the optical waveguide such that at least a portion of the core is exposed so as to emit light from a side surface of the core, the side surface extending in the first direction, and configured to apply the light to hair growing on a skin; and
a connecting member integrally joined to the light emitting module such that the connecting member retains an end of the optical waveguide, the connecting member configured to position the core with respect to light introduced into the optical waveguide, wherein:
the core is disposed off-center toward an outer circumference of the cladding and a part of the side surface of the core is exposed from the cladding,
the connecting member is mechanically connectable to a connection target, and
the core is configured so that light is introduced from an end of the core that faces the connection target.
