Zusammenfassung:A multicore optical fiber, includes: a core which is formed of silica glass doped with at least fluorine, the core having a relative refractive index difference with respect to a refractive index of silica as a reference being -0.30% to -0.10%; and a clad that is formed of silica glass doped with at least fluorine, the clad including a first clad surrounding an outer periphery of the core and a second clad provided outside the first clad, in which a relative refractive index difference between the first clad and the core is 0.8% or more, and a refractive index of the second clad is higher than a refractive index of the first clad and lower than a refractive index of the core.
