An object of the present invention is to provide a polycarbonate which is excellent in mechanical strength, has heat resistance, has a small refractive index, has a large Abbe number, is small in birefringence, and is excellent in transparency. The polycarbonate of the present invention is obtained by melt-polycondensation of a dihydroxy compound containing a dihydroxy compound having at least one linking group -CH2-O- in a molecule, and a comparative viscosity of 0.40 dl/g or more and 1.70. Below dl/g, the formic acid content is less than 5 ppm by weight. |
