Abstract
The object of the present invention is to provide a binder pitch increased in carbonization yield (fixed carbon content) without varying the softening point thereof. A binder pitch has a carbon-to-hydrogen molar ratio of 1.90 or more, a quinoline insoluble content of 12.0% to 30.0% by mass, a free carbon content of 12.0% to 30.0% by mass, a mesophase content of 0.50% by mass or less, a toluene insoluble content of 24.0% by mass or more, and a fixed carbon content of 58.0% by mass or more.
