Abstract

A method for producing a binder pitch for a carbon material, comprising heat-treating a petroleum-based heavy oil (step 1); distilling the heat-treated product obtained in step 1 to obtain a base pitch having a softening point of 60°C or more and 110°C or less, a fixed carbon content of 50.0% by mass or more, an initial boiling point of 320°C or more and 450°C or less, and a quinoline insoluble matter (QI) of 1.0% by mass or less as a high boiling point component (step 2); adding carbon powder to the base pitch obtained in step 2 and mixing them (step 3).
