PROBLEM TO BE SOLVED: To provide a polycarbonate resin having excellent transparency and heat resistance and having extremely low light absorption particularly in the near infrared region, a method for producing the same, and low transmission loss in the near infrared region. A plastic optical waveguide is provided. SOLUTION: This is obtained by reacting a dihydric phenol mainly comprising 2,2-bis (4-hydroxyphenyl) -1,1,1,3,3,3-hexafluoropropane with a carbonate precursor, And, a polycarbonate resin having a specific fluorine-substituted phenoxy group at the resin terminal, A method for producing the resin using a predetermined fluorine-substituted phenol, and a plastic optical waveguide using the resin for a core portion. |
