An optical fiber has a single-layer coated optical fiber having an optical bare fiber including a core and a clad formed around the core, and a single coating layer provided around an outer periphery of the optical bare fiber, an inner coating layer provided around an outer periphery of the single-layer coated optical fiber, which contacts with the single coating layer, and an outer coating layer formed as a collective coating layer around an outer side of the inner coating layer. The inner coating layer has a Young modulus lower than a Young modulus of the single coating layer and a Young modulus of the outer coating layer.
