Abstract:
The present invention relates to an optical waveguide containing: a core formed by curing (A) a fluorine-containing polyarylene prepolymer having a crosslinkable functional group; and a cladding formed by curing (I) a curable composition containing (B) a compound having a molecular weight of 140 to 5,000, having a crosslinkable functional group and having no fluorine atom, and (A) a fluorine-containing polyarylene prepolymer.
