Abstract
An optical fiber comprises a glass portion comprising a core and a cladding surrounding the core, and, a resin portion comprising a non-removable resin layer tightly covering the glass portion and comprising an ultraviolet curing resin and a buffer layer covering the non-removable resin layer and comprising an ultraviolet curing resin. A diameter of the core falls within a range from 20 μm or larger to 80 μm or smaller, and an outer diameter of the non-removable resin layer falls within a range from 120 μm or larger to 127 μm or smaller. In this optical fiber, when flexural rigidity of the glass portion is EI(g) and flexural rigidity of the resin portion is EI(r), EI(g)≧EI(r) is satisfied.
