Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a fluorine-containing oxetane copolymer suitable for a cladding material or the like for an optical transmission fiber, excellent in adhesiveness to a base material and transparency of the resin and having a low refractive index or the like, and a manufacturing method of the same, a composition using the same and a cured product. SOLUTION: The present invention provides the fluorine-containing oxetane copolymer containing a monomer unit of formula (1) [R is H, F, an alkyl, a fluoroalkyl, an aryl, allyl, furyl or thienyl; Rf is a monovalent fluorine- containing group shown by the formula: CnF2n-1, CnF2nH or CnF2n+1 (n is an integer from 2 to 12) and m is an integer from 1 to 10], the manufacturing method, the composition and the cured material.
