The present invention relates to an isotropic pitch for manufacturing a carbon fiber and a method for preparing the same, wherein an isotropic pitch having particular ranges of a softening point, viscosity, a molecular weight, and a crystal structure can be prepared, and such a feature can maximize mechanical properties of the carbon fiber by maximally suppressing the generation of insoluble solids and mesophase of the pitch, and can also reduce energy consumption since a carbonization process is performed at a low temperature. |
