Abstract
A light guide unit includes a light guide member and a protection member surrounding the light guide member. The light guide member includes an optical fiber having an outer diameter. The protection member is formed in a network structure by knitting a metal member having a flat cross-sectional shape by bending the metal member in a direction in which the thickness of the metal material is thin, and a gap smaller than the outer diameter is formed along the axial direction.
