PROBLEM TO BE SOLVED: To provide a method for easily and precisely measuring the friction coefficient of coated optical fibers. SOLUTION: The face of a moving substrate 20b where the coated optical fibers, 10b are adhered and fixed is made to face the face of a fixed substrate 20a where the coated optical fiber 10a is adhered and fixed and the coated optical fiber 10a and 10b are arranged perpendicularly to each other. In the method of measuring the friction coefficient of a coated optical fiber, an adjusting weight 30 is placed on the moving substrate 20b, the moving substrate 20b is pulled in a direction shown by A at constant speed by a load cell and modulus, namely, friction force required for it is measured.
